OK. From your original report, I assumed that lsusb didn't work.

It just parses /proc/bus/usb/devices. By contrast, lsusb actually opens each of the files in /proc/bus/usb/XXX/YYY (where XXX is the various busses, and YYY is the device on that bus). 2. I'm not sure of a way for testing for the language settings. If you aren't worried about the language, just comment out that part of the lsusb code. Brad -- http://conf.linux.org.au. 22-25Jan2003.
