I assume this device will expose other serial functions when booted in
application USB mode?  But probably not with a Gobi 2k layout... Maybe
add the application device ID to some USB serial driver too, and include
the QDL device ID there as well to reduce confusion?

Could you provide a view of the default USB descriptors in both QDL and
application mode?  E.g from lsusb -v or  /sys/kernel/debug/usb/devices?
