Of course it's device-dependent! Obviously things like maxPacketSize and endpoint addresses will be different for different devices. However it is not driver-dependent (other than the driver name). > should this question be posed in linux-usb-devel? Yes it should; the USB users don't control the direction of future changes. But you'd probably get about the same answer as I'm giving you. In general, the feeling probably is that /proc/bus/usb/devices is there for a reason, so you should use it.
