Forcing driver to device match

Question

Find the module in the sysfs tree. In this case it was in

/sys/bus/usb-serial/drivers/cp2101

In this directory, there is a new_id file entry that can be used to dynamically add VID PID pair like this :

echo VID PID >new_id

Here is a LWN entry about this feature

In case you want to make this change permanent and assign specific driver to device (VID, PID) you may find this answer useful.

For example create new file/etc/udev/rules.d/98-joystick.rules with content:

ACTION=="add", ATTRS{idVendor}=="1345", ATTRS{idProduct}=="6005", RUN+="/sbin/modprobe xpad" RUN+="/bin/sh -c 'echo 1345 6005 > /sys/bus/usb/drivers/xpad/new_id'"

Replace 1345 with your VID and 6005 with your PID.

Replace xpad with appropriate driver.

Run following command:

$ sudo udevadm control --reload

Unplug and plug your device back and check if the new driver is loaded.

Example shown here is for fixing driver issues with Speedlink Strike FX Gamepad (SL-6537-BK)

You don't need actually recompile the whole kernel, recompiling only relevant kernel module with updated match table will be enough, in case that this answer, does not work on your kernel.
