We need to know that as odds are the generic driver is _not_ the proper way to control these devices.

Yes, you can add new device ids to the generic usb-serial driver after it has been loaded, that would work, but again, it's not the nicest way. > > Regards, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
