Forcing driver to device match

I have a piece of usb hardware, for which I know the driver. However, the vendor id and product id do not match the VID, PID pair registered in the driver. Is there a way in linux to force a driver to be associated with a known device, that do not involve kernel module recompilation to add a PID / VID pair ?

Answer

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
