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. CDC-ACM oh, thanks. There is always at least one more typo in any document… This file is an official description how to use it: Documentation/usb/usb-serial.txt But it is outdated.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. This is simply not true. The vendor and module parameters are still there for usbserial (i.e. the generic driver). Would you mind updating this patch to document the sysfs-method as an alternative instead? Using sysfs is preferred as that functionality can be used with any usb-serial driver and the drivers can also be compiled in. Hm. For me it did not work as described and therefore I searched for and found the solution cited below, which appears to confirm that it does not work any more. Only with these hints to use the /sys approach I could make it working immediately. Therefore I assumed that the documentation is outdated. But it might also be a hidden bug with the parameter passing. I had tested on 4.0-rc3. I can try a little more but it might be waste of time to find out why the old does not work, if there is a preferred method now. 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.
