Quite possibly - shouldn't /proc/bus/usb/devices (or one of the /proc...usb...devices ) gives some clues about what kind of interface/device-class it is? lsusb probably also... > > Jul 3 00:12:18 localhost kernel: [27988.288783] > usb 5-2: New USB device found, idVendor=10c5, > idProduct=819a > > Jul 3 00:12:18 localhost kernel: [27988.288787] > usb 5-2: New USB device strings: Mfr=1, Product=2, > SerialNumber=0 > > Jul 3 00:12:18 localhost kernel: [27988.288789] > usb 5-2: Manufacturer: www.rding.cn The vendor's web site has some sort of linux driver for something else.
