Ori,
The Gigabeat has the ability to run in MTP or "USB" mode, at least with the original firmware.

I tried to reinstall the original firmware to no avail. I do wonder what lsusb would say if you changed the "mode" in the original firmware.
If lsusb doesn't change for the modes, rockbox should update its usb id to match the original firmware.
