I have a new usb dongle Huawei E3531 trying to support in my h/w having old kernel version 2.6.16. I use usb_modeswitch to change the mode from usb storage to modem manually. As I do not have udev rule support in my h/w, I need an alternative way of mode switching during plugin time automatically. For that I have added the default device and vendor id in unusual_devs.h with UNUSUAL_DEV() macro to ignore the storage driver in the first place and added the target device and vendor id in the option.c to get the option driver loaded on related interface. Below is the default and target entries mention in the usb_modeswitch help. /root # usb_modeswitch -h Usage: usb_modeswitch [<params>] [-c filename] -v, --default-vendor NUM vendor ID of original mode (mandatory) -p, --default-product NUM product ID of original mode (mandatory) -V, --target-vendor NUM target mode vendor ID (optional) -P, --target-product NUM target mode product ID (optional) -C, --target-class NUM target mode device class (optional) On Wed, Feb 18, 2015 at 1:09 PM, Clemens Ladisch <clemens@xxxxxxxxxx> wrote: > temp sha wrote: >> Can any one brief me about the concept of default/target product id /vendor id ? > > These are not terms that have a well-known meaning.
