No, not good. You must not unbind this driver if you want to use the device. > But... the following command to bind to the new driver throws an error: > [EMAIL PROTECTED] /]# echo -n "3-1" > /sys/bus/usb/drivers/usbfs/bind > -bash: echo: write error: No such device That's because you don't bind usbfs to a device through sysfs. You bind it by running a program that calls the USBDEVFS_CLAIMINTERFACE ioctl.
