I don't know if this was what Greg meant, but you can always use /sys/bus/usb/drivers/usbhid/unbind to unbind the device from the usbhid driver. Then you can manually bind it to some other driver supporting the same device using the same mechanism (with s/un// of course), or load another supporting driver to make it probe and bind the device. Hmm, I was going to point you to the file documenting bind/unbind for the usb bus, but it doesn't seem to exist? There you have a task for someone wanting to improve the docs :) Anyway, it goes like this: Look at the device driver binding in sysfs: $ ls -l /sys/bus/usb/drivers/usbhid total 0 lrwxrwxrwx 1 root root 0 Nov 13 09:06 4-4:1.0 -> ../../../../devices/pci0000:00/0000:00:1d.7/usb4/4-4/4-4:1.0 --w------- 1 root root 4096 Nov 13 09:06 bind lrwxrwxrwx 1 root root 0 Nov 13 09:06 module -> ../../../../module/usbhid -rw-r--r-- 1 root root 4096 Nov 13 09:06 new_id -rw-r--r-- 1 root root 4096 Nov 13 09:06 remove_id --w------- 1 root root 4096 Nov 13 09:06 uevent --w------- 1 root root 4096 Nov 13 09:06 unbind Unbind the device you want to move somewhere else: $ echo 4-4:1.0 >/sys/bus/usb/drivers/usbhid/unbind Bind it to 'otherdriver': $ echo 4-4:1.0 >/sys/bus/usb/drivers/'otherdriver'/bind (wich will only succeed of that driver's probe succeeds, of course. If you need to add a device ID to another driver, then do that using 'new_id' instead. Which will trigger automatic probing of 'free' devices) Bjørn _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
