Huh? /dev/usb/hiddev0 is major 180, minor 96. So the kernel asked for
minor 96 and it got it. Why are you trying to connect to minor number
192?

For a list of the USB minor numbers see:
http://www.linux-usb.org/usb.devices.txt

It's a bit different from Documentation/devices.txt, I need to send the
updates to lanana.org someday...
