[libhid-discuss] Find the path...

[Charles Lepple]

That doesn't sound right. If you re-plug the device, the kernel  
usbhid driver will claim it again, but running test_libhid (or libhid- 
detach-device, also included in libhid) should make lsusb show the  
descriptor.

Are there any errors in dmesg?

Do you have read+write permissions to the device node (in /proc/bus/ 
usb or /dev/bus/usb)?

What does "cat /proc/bus/usb/devices" say?
