I have deployed ADSelfService Plus onto an ESX 5.5 environment but am struggling to get a USB GSM modem working on it due I think to the nature of the way ESX is handling the USB pass through. Has anyone else managed to get this setup and working and if so what modem did you end up using.

This is the last hurdle that I need to get completed before I can start rolling this out to my user and is the part which seems to have the least up to date documentation around it

Many thanks 

Mark.
