USB devices announce their capabilities in their descriptors. Please
post the output of lsusb and the output of "od -t x1
/proc/bus/usb/001/xxx" (xxx is the device number; try all files
there, the one I want to see has "1E 04" somewhere in the first
line).
As requested:
1) lsusb

2) The od is attached as a .txt file.
3) Perhaps easier to use is the output of usbview,
also attached as a .txt file.
