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...
