Recently the Huawei e3276 devices my company was buying came with a new firmware version and the word "hilink" printed all over them. Instead of showing up as a usbserial device using the option driver, they show up now as an ethernet device. While I can see the convenience factor in this, it doesn't serve our purpose, so some quick googling showed me I can enable the serial again with usb_modeswitch and this line: 55534243123456780000000000000011062000000000000200000000000000 When I do this, the usbid changes to 12d1:1566 and using the option driver works properly with the device. The problem I have, is that we are currently using kernel 3.18 and it doesn't have that usbid for my device. Things work properly when I run this: echo "12d1 1566" > /sys/bus/usb-serial/drivers/option1/new_id My problem is, I was hoping to find a better way to handle this than having to run a script to do this at boot. I tried adding the vendor and product to usbserial using /etc/modprobe.d, however, this causes it to use the usbserial generic module instead of the option module and doesn't work. Can anyone assist me in finding a proper solution instead of echoing to new_id on boot? Additionally, it would be nice to officially add this id to the option driver, it looks like it's not present at this time: https://git.kernel.org/cgit/linux/kernel/git/gregkh/usb.git/tree/drivers/usb/serial/option.c I can submit a patch to add it if desired, but right now it would be super helpful if I can make this work without a kernel patch.
