I missconfigured the usb interface - factory reset?

[tswaehn]

I did missconfigure the module by setting

AT+CUSBPIDSWITCH=9007

now there is no USB CDC device available that I can use for serial communication

Is there a way to factory reset it back to default 9001 or 9011 (which worked nicely before)
