Are you saying there is another place I need to add the IDs?
Right now I’m thinking my problem is with the kernel.
Although I have added in the CONFIG_USB_SERIAL_OPTION option, it doesn’t seem to be making its way into the compiled kernel.
When I check the kernel’s .config file (looking at out/target/product/msm8909w/obj/KERNEL_OBJ/.config for my Android build, OR from the shell by looking at /proc/config.gz) CONFIG_USB_SERIAL_OPTION is not present.
ps: in case someone else needs to know the command to check the .config from shell: cat /proc/config.gz | gunzip | grep SERIAL_OPTION
