From: "H. Nikolaus Schaller" <h...@goldelico.com> While trying to test the Pyra GSM/GPS/3G module I had reconfigured the USB interface by mistake and therefore needed to run a different USB driver than CSC-ACM. It turned out that I need the "usbserial" driver.
This file is an official description how to use it: Documentation/usb/usb-serial.txt But it is outdated. The parameters vendor= and product= are no longer available since ca. 3.12 which means that documentation is lagging behind quite some time. Here was the solution: https://bbs.archlinux.org/viewtopic.php?id=175499 insmod usbserial vendor=0x#### product=0x#### becomes (first #### is vendor, second is product) modprobe usbserial echo #### #### >/sys/bus/usb-serial/drivers/generic/new_id This patch changes the documentation file as needed.
