I have two USB devices that when plugged in must have COM ports 3 & 4 assigned, my question is how can I do this using a batch file?

The two devices are a GEWA Transmitter (FTDIBUS\VID_0403+PID_6001+AI04WJT5A\0000) (needs to be COM3) and an ELDAT transmitter (USB\VID_155A&PID_1006\00005987) (needs to be on COM4)

Cheers
