I am running 2.6.17-1.2145_FC5xen0 and I am having a serious problem trying to manually bind a driver to a USB device ( Velleman k8055 ).
The device seems to automatically bind to /sys/bus/usb/drivers/usb instead of /sys/bus/usb/drivers/usbfs ( which I am semi-sure is what the device needs to be using ). I have trawled the web and spent many hours on trial and error but I am seriously stuck
running
Code:
echo -n "3-1" > /sys/bus/usb/drivers/usb/unbind
seems to unbind the device from the driver ok. After unbinding, the "driver" symlink disappears from the /sys/bus/usb/devices/3-1/ directory. And the "3-1" symlink disappears from the /sys/bus/usb/drivers/usb directory. Which all shows that the unbind worked
But then I can't bind it to the usbfs driver using /sys/bus/usb/drivers/usbfs/bind.
Code:
[root@safe /]# echo -n "3-1" > /sys/bus/usb/drivers/usbfs/bind
-bash: echo: write error: No such device
Neither can I bind it back onto /sys/bus/usb/drivers/usb/bind
Before unbinding:
Code:
[root@safe]# ls -la /sys/bus/usb/drivers/usb/
