Add them to the blacklist. Signed-off-by: Remi Cattiau <remi@xxxxxxxxxxx> Signed-off-by: Jiri Kosina <jkosina@xxxxxxx> The problem apparently [1] is, that the vendor has been super-creative and assigned the same combination of idVendor/idProduct to completely different devices. Oh well. Remi, could you please check your device against the lsusb data provided in bugzilla to check whether there is any possibility to distinguish these devices, so that we could put some ugly check in place probably? Thanks.
