See the individual product section below for specific information about the different devices. CONFIGURATION Currently the driver can handle up to 256 different serial interfaces at one time. If you are not using devfs: The major number that the driver uses is 188 so to use the driver, create the following nodes: mknod /dev/ttyUSB0 c 188 0 mknod /dev/ttyUSB1 c 188 1 mknod /dev/ttyUSB2 c 188 2 mknod /dev/ttyUSB3 c 188 3 . . . mknod /dev/ttyUSB254 c 188 254 mknod /dev/ttyUSB255 c 188 255 If you are using devfs: The devices supported by this driver will show up as /dev/usb/tts/{0,1,...} When the device is connected and recognized by the driver, the driver will print to the system log, which node(s) the device has been bound to. SPECIFIC DEVICES SUPPORTED ConnectTech WhiteHEAT 4 port converter ConnectTech has been very forthcoming with information about their device, including providing a unit to test with. The driver is officially supported by Connect Tech Inc. http://www.connecttech.com For any questions or problems with this driver, please contact Stuart MacDonald at stuartm@connecttech.com HandSpring Visor, Palm USB, and Clié USB driver This driver works with all HandSpring USB, Palm USB, and Sony Clié USB devices. Only when the device tries to connect to the host, will the device show up to the host as a valid USB device. When this happens, the device is properly enumerated, assigned a port, and then communication _should_ be possible. The driver cleans up properly when the device is removed, or the connection is canceled on the device. NOTE: This means that in order to talk to the device, the sync button must be pressed BEFORE trying to get any program to communicate to the device. This goes against the current documentation for pilot-xfer and other packages, but is the only way that it will work due to the hardware in the device. When the device is connected, try talking to it on the second port (this is usually /dev/ttyUSB1 if you do not have any other usb-serial devices in the system.) The system log should tell you which port is the port to use for the HotSync transfer. The "Generic" port can be used for other device communication, such as a PPP link. For some Sony Clié devices, /dev/ttyUSB0 must be used to talk to the device. This is true for all OS version 3.5 devices, and most devices that have had a flash upgrade to a newer version of the OS. See the kernel system log for information on which is the correct port to use. If after pressing the sync button, nothing shows up in the system log, try resetting the device, first a hot reset, and then a cold reset if necessary. Some devices need this before they can talk to the USB port properly. Devices that are not compiled into the kernel can be specified with module parameters. e.g. modprobe visor vendor=0x54c product=0x66 There is a webpage and mailing lists for this portion of the driver at: http://usbvisor.sourceforge.net/ For any questions or problems with this driver, please contact Greg Kroah-Hartman at greg@kroah.com PocketPC PDA Driver This driver can be used to connect to Compaq iPAQ, HP Jornada, Casio EM500 and other PDAs running Windows CE 3.0 or PocketPC 2002 using a USB cable/cradle. Most devices supported by ActiveSync are supported out of the box. For others, please use module parameters to specify the product and vendor id. e.g. modprobe ipaq vendor=0x3f0 product=0x1125 The driver presents a serial interface (usually on /dev/ttyUSB0) over which one may run ppp and establish a TCP/IP link to the PDA. Once this is done, you can transfer files, backup, download email etc. The most significant advantage of using USB is speed - I can get 73 to 113 kbytes/sec for download/upload to my iPAQ. This driver is only one of a set of components required to utilize the USB connection. Please visit http://synce.sourceforge.net which contains the necessary packages and a simple step-by-step howto. Once connected, you can use Win CE programs like ftpView, Pocket Outlook from the PDA and xcerdisp, synce utilities from the Linux side. To use Pocket IE, follow the instructions given at http://www.tekguru.co.uk/EM500/usbtonet.htm to achieve the same thing on Win98. Omit the proxy server part; Linux is quite capable of forwarding packets unlike Win98. Another modification is required at least for the iPAQ - disable autosync by going to the Start/Settings/Connections menu and unchecking the "Automatically synchronize ..." box. Go to Start/Programs/Connections, connect the cable and select "usbdial" (or whatever you named your new USB connection). You should finally wind up with a "Connected to usbdial" window with status shown as connected. Now start up PIE and browse away. If it doesn't work for some reason, load both the usbserial and ipaq module with the module parameter "debug" set to 1 and examine the system log. You can also try soft-resetting your PDA before attempting a connection. Other functionality may be possible depending on your PDA. According to Wes Cilldhaire <billybobjoehenrybob@hotmail.com>, with the Toshiba E570, ...if you boot into the bootloader (hold down the power when hitting the reset button, continuing to hold onto the power until the bootloader screen is displayed), then put it in the cradle with the ipaq driver loaded, open a terminal on /dev/ttyUSB0, it gives you a "USB Reflash" terminal, which can be used to flash the ROM, as well as the microP code.. so much for needing Toshiba's $350 serial cable for flashing!! :D NOTE: This has NOT been tested. Use at your own risk. For any questions or problems with the driver, please contact Ganesh Varadarajan <ganesh@veritas.com> Keyspan PDA Serial Adapter Single port DB-9 serial adapter, pushed as a PDA adapter for iMacs (mostly sold in Macintosh catalogs, comes in a translucent white/green dongle). Fairly simple device. Firmware is homebrew. This driver also works for the Xircom/Entrgra single port serial adapter. Current status: Things that work: basic input/output (tested with 'cu') blocking write when serial line can't keep up changing baud rates (up to 115200) getting/setting modem control pins (TIOCM{GET,SET,BIS,BIC}) sending break (although duration looks suspect) Things that don't: device strings (as logged by kernel) have trailing binary garbage device ID isn't right, might collide with other Keyspan products changing baud rates ought to flush tx/rx to avoid mangled half characters Big Things on the todo list: parity, 7 vs 8 bits per char, 1 or 2 stop bits HW flow control not all of the standard USB descriptors are handled: Get_Status, Set_Feature O_NONBLOCK, select() For any questions or problems with this driver, please contact Brian Warner at warner@lothar.com Keyspan USA-series Serial Adapters Single, Dual and Quad port adapters - driver uses Keyspan supplied firmware and is being developed with their support. Current status: The USA-18X, USA-28X, USA-19, USA-19W and USA-49W are supported and have been pretty throughly tested at various baud rates with 8-N-1 character settings. Other character lengths and parity setups are presently untested. The USA-28 isn't yet supported though doing so should be pretty straightforward. Contact the maintainer if you require this functionality. More information is available at: http://misc.nu/hugh/keyspan.html For any questions or problems with this driver, please contact Hugh Blemings at hugh@misc.nu FTDI Single Port Serial Driver This is a single port DB-25 serial adapter. More information about this device and the Linux driver can be found at: http://reality.sgi.com/bryder_wellington/ftdi_sio/ For any questions or problems with this driver, please contact Bill Ryder at bryder@sgi.com ZyXEL omni.net lcd plus ISDN TA This is an ISDN TA. Please report both successes and troubles to azummo@towertech.it Cypress M8 CY4601 Family Serial Driver This driver was in most part developed by Neil "koyama" Whelchel. It has been improved since that previous form to support dynamic serial line settings and improved line handling. The driver is for the most part stable and has been tested on an smp machine. (dual p2) Chipsets supported under CY4601 family: CY7C63723, CY7C63742, CY7C63743, CY7C64013 Devices supported: -DeLorme's USB Earthmate (SiRF Star II lp arch) -Cypress HID->COM RS232 adapter Note: Cypress Semiconductor claims no affiliation with the the hid->com device. Most devices using chipsets under the CY4601 family should work with the driver. As long as they stay true to the CY4601 usbserial specification. Technical notes: The Earthmate starts out at 4800 8N1 by default... the driver will upon start init to this setting. usbserial core provides the rest of the termios settings, along with some custom termios so that the output is in proper format and parsable. The device can be put into sirf mode by issuing NMEA command: $PSRF100,<protocol>,<baud>,<databits>,<stopbits>,<parity>*CHECKSUM $PSRF100,0,9600,8,1,0*0C It should then be sufficient to change the port termios to match this to begin communicating. As far as I can tell it supports pretty much every sirf command as documented online available with firmware 2.31, with some unknown message ids. The hid->com adapter can run at a maximum baud of 115200bps. Please note that the device has trouble or is incapable of raising line voltage properly. It will be fine with null modem links, as long as you do not try to link two together without hacking the adapter to set the line high. The driver is smp safe. Performance with the driver is rather low when using it for transfering files. This is being worked on, but I would be willing to accept patches. An urb queue or packet buffer would likely fit the bill here. If you have any questions, problems, patches, feature requests, etc. you can contact me here via email: dignome@gmail.com (your problems/patches can alternately be submitted to usb-devel) Digi AccelePort Driver This driver supports the Digi AccelePort USB 2 and 4 devices, 2 port (plus a parallel port) and 4 port USB serial converters. The driver does NOT yet support the Digi AccelePort USB 8. This driver works under SMP with the usb-uhci driver. It does not work under SMP with the uhci driver. The driver is generally working, though we still have a few more ioctls to implement and final testing and debugging to do. The paralled port on the USB 2 is supported as a serial to parallel converter; in other words, it appears as another USB serial port on Linux, even though physically it is really a parallel port. The Digi Acceleport USB 8 is not yet supported. Please contact Peter Berger (pberger@brimson.com) or Al Borchers (alborchers@steinerpoint.com) for questions or problems with this driver. Belkin USB Serial Adapter F5U103 Single port DB-9/PS-2 serial adapter from Belkin with firmware by eTEK Labs. The Peracom single port serial adapter also works with this driver, as well as the GoHubs adapter. Current status: The following have been tested and work: Baud rate 300-230400 Data bits 5-8 Stop bits 1-2 Parity N,E,O,M,S Handshake None, Software (XON/XOFF), Hardware (CTSRTS,CTSDTR)* Break Set and clear Line contrl Input/Output query and control ** * Hardware input flow control is only enabled for firmware levels above 2.06. Read source code comments describing Belkin firmware errata. Hardware output flow control is working for all firmware versions. ** Queries of inputs (CTS,DSR,CD,RI) show the last reported state. Queries of outputs (DTR,RTS) show the last requested state and may not reflect current state as set by automatic hardware flow control. TO DO List: -- Add true modem contol line query capability. Currently tracks the states reported by the interrupt and the states requested. -- Add error reporting back to application for UART error conditions. -- Add support for flush ioctls. -- Add everything else that is missing :) For any questions or problems with this driver, please contact William Greathouse at wgreathouse@smva.com Empeg empeg-car Mark I/II Driver This is an experimental driver to provide connectivity support for the client synchronization tools for an Empeg empeg-car mp3 player. Tips: * Don't forget to create the device nodes for ttyUSB{0,1,2,...} * modprobe empeg (modprobe is your friend) * emptool --usb /dev/ttyUSB0 (or whatever you named your device node) For any questions or problems with this driver, please contact Gary Brubaker at xavyer@ix.netcom.com MCT USB Single Port Serial Adapter U232 This driver is for the MCT USB-RS232 Converter (25 pin, Model No. U232-P25) from Magic Control Technology Corp. (there is also a 9 pin Model No. U232-P9). More information about this device can be found at the manufacture's web-site: http://www.mct.com.tw. The driver is generally working, though it still needs some more testing. It is derived from the Belkin USB Serial Adapter F5U103 driver and its TODO list is valid for this driver as well. This driver has also been found to work for other products, which have the same Vendor ID but different Product IDs. Sitecom's U232-P25 serial converter uses Product ID 0x230 and Vendor ID 0x711 and works with this driver. Also, D-Link's DU-H3SP USB BAY also works with this driver. For any questions or problems with this driver, please contact Wolfgang Grandegger at wolfgang@ces.ch Inside Out Networks Edgeport Driver This driver supports all devices made by Inside Out Networks, specifically the following models: Edgeport/4 Rapidport/4 Edgeport/4t Edgeport/2 Edgeport/4i Edgeport/2i Edgeport/421 Edgeport/21 Edgeport/8 Edgeport/8 Dual Edgeport/2D8 Edgeport/4D8 Edgeport/8i Edgeport/2 DIN Edgeport/4 DIN Edgeport/16 Dual For any questions or problems with this driver, please contact Greg Kroah-Hartman at greg@kroah.com REINER SCT cyberJack pinpad/e-com USB chipcard reader Interface to ISO 7816 compatible contactbased chipcards, e.g. GSM SIMs. Current status: This is the kernel part of the driver for this USB card reader. There is also a user part for a CT-API driver available. A site for downloading is TBA. For now, you can request it from the maintainer (linux-usb@sii.li). For any questions or problems with this driver, please contact linux-usb@sii.li Prolific PL2303 Driver This driver support any device that has the PL2303 chip from Prolific in it. This includes a number of single port USB to serial converters and USB GPS devices. Devices from Aten (the UC-232) and IO-Data work with this driver. For any questions or problems with this driver, please contact Greg Kroah-Hartman at greg@kroah.com KL5KUSB105 chipset / PalmConnect USB single-port adapter Current status: The driver was put together by looking at the usb bus transactions done by Palm's driver under Windows, so a lot of functionality is still missing. Notably, serial ioctls are sometimes faked or not yet implemented. Support for finding out about DSR and CTS line status is however implemented (though not nicely), so your favorite autopilot(1) and pilot-manager -daemon calls will work. Baud rates up to 115200 are supported, but handshaking (software or hardware) is not, which is why it is wise to cut down on the rate used is wise for large transfers until this is settled. Options supported: If this driver is compiled as a module you can pass the following options to it: debug - extra verbose debugging info (default: 0; nonzero enables) use_lowlatency - use low_latency flag to speed up tty layer when reading from from the device. (default: 0; nonzero enables) See http://www.uuhaus.de/linux/palmconnect.html for up-to-date information on this driver. Generic Serial driver If your device is not one of the above listed devices, compatible with the above models, you can try out the "generic" interface. This interface does not provide any type of control messages sent to the device, and does not support any kind of device flow control. All that is required of your device is that it has at least one bulk in endpoint, or one bulk out endpoint. To enable the generic driver to recognize your device, build the driver as a module and load it by the following invocation: insmod usbserial vendor=0x#### product=0x#### where the #### is replaced with the hex representation of your device's vendor id and product id. This driver has been successfully used to connect to the NetChip USB development board, providing a way to develop USB firmware without having to write a custom driver. For any questions or problems with this driver, please contact Greg Kroah-Hartman at greg@kroah.com CONTACT: If anyone has any problems using these drivers, with any of the above specified products, please contact the specific driver's author listed above, or join the Linux-USB mailing list (information on joining the mailing list, as well as a link to its searchable archive is at http://www.linux-usb.org/ ) Greg Kroah-Hartman greg@kroah.com |
