Lsusb (Linux)

From EdWiki

The lsusb command provided in Ubuntu Linux provides information about USB devices connected to your computer. To use lsusb, open a terminal window and type:

sudo lsusb

This will display a list of all USB devices connected to your computer. Look for the hardware you want to use with OpenOCD. For the EK-TM4C123GXL Board you should see something like this:

Bus 001 Device 005: ID 1cbe:00fd Luminary Micro Inc. In-Circuit Debug Interface

The bus number and device number will likely be different, but take note of them. Now get more information about the device by typing:

sudo lsusb -v -s [BUS_NUMBER]:[DEVICE_NUMBER]

For example, if you had seen the output listed above, you would type:

sudo lsusb -v -s 002:006

Scroll up through the information about your hardware. For the original CEDT, you should see something like this:

 idVendor           0x1cbe Luminary Micro Inc.
 idProduct          0x00fd In-Circuit Debug Interface
 bcdDevice            1.00
 iManufacturer           1 Texas Instruments
 iProduct                2 In-Circuit Debug Interface
 iSerial                 3 0E21127D

Pay careful attention to the values following idVendor, idProduct, iProduct, and iSerial. If those values for your hardware don't match the values listed above, OpenOCD won't recognize the EK-TM4C123GXL Board.

If lsusb doesn't show the values you expect for your hardware, there may be a problem with the hardware itself or with your USB drivers.
