I'll look in to it. I already have a few patches here (part of a larger 3.11 clean-up series) which removes the vid/pid module parameters from all usb-serial modules including ti_usb_3410_5052. I hope to be able to submit the whole series a later tonight, but here's the ti_usb_3410_5052 part if anyone's interested. Thanks, Johan From: Johan Hovold <jhovold@xxxxxxxxx> Subject: [PATCH] USB: ti_usb_3410_5052: remove vendor/product module parameters Remove the vendor and product module parameters which were added a long time ago when we did not have the dynamic sysfs interface to add new device ids (and which isn't limited to five new vid/pid pair). A vid/pid pair can be added dynamically using sysfs, for example: echo 0451 1234 >/sys/bus/usb-serial/drivers/ti_usb_3410_5052_1/new_id for 1-port adapters, or echo 0451 1234 >/sys/bus/usb-serial/drivers/ti_usb_3410_5052_2/new_id for 2-port adapters.
