Linux上无法识别的USB设备

Question

I have car diagnostic device ELM327 with usb port connection, but Mint can't recognize it. Here is the list of devices from terminal:

~ $ lsusb
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 09da:000e A4 Tech Co., Ltd
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 003: ID 7073:3037
Bus 003 Device 002: ID 046d:c215 Logitech, Inc. Extreme 3D Pro
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

That device is listed as "Bus 003 Device 003" and, as you can see, has no description.

Any suggestions? Does it have some further procedure to been recognized by auto-data software? Cant find this solved problem googleing.

Thanks!

Answer 1

lsusb merely translates the IDs (provided by the device) into text strings, using /usr/share/usb.ids . That does not say anything about the (un)availability of a driver.

Answer 2

I found other people who had the same problem as you by googling: Here and Here (in Polish) .

"It says FTDI, manufacturer of the device, has a Linux driver to be able to use this interface as a serial port."

Knowing that you might try the FTDI site . EDIT: The FTDI site says that it is supported natively in kernel 2.6.31 and later. See also the FTDI driver sourceforge project .

Note that none of this tells you what protocol you speak to it.
