ja, now add the line: none /proc/bus/usb usbdevfs defaults 0 0 to fstab, and mount -a again after that you have the linux usb core pseudo filesystem, in which you should find a /proc/bus/usb/devices file that shows all usb devices. > How can I see the files in my u-disk? I don't know what a u-disk is, but usb sticks are normally mounted using the scsi emulation layer.
