Module parameters are for the 1990's, they are global and horrible to try to work with. You should provide something on a per-device basis, as what happens if your system requires different things here for different devices? You set this for all devices :( [...]
Hi
do you think something like what the usbcore has would be better? A module parameter like "quirks=<vendor-id>:<product-id>:<flags>[,<vendor-id>:<product-id>:<flags>]*"?
Not really, that's just for debugging, and asking users to test something, not for a final solution to anything.
thanks,
