Para compilar los modulos y configurarlos puedes probar asi:
As example for me (*.ko files on SD card)
insmod /sdcard/bluetooth.ko
insmod /sdcard/btusb.ko
After that connect your bt-stick to MID.
External USB-GPS with PL2303 may work in this MID.
------------------------------------------------------------------------------------
Using insmod pl2303.ko installs the driver to ttyUSB0, cat /dev/ttyUSB0 shows gps data packets coming back from my ND-100S gps dongle OK.
Simple type in adb shell:
insmod /path/to/module.ko
