Not enough only to have tms reciever with mini-usb, there is many different protocols which use tmc recievers, and you need appropriate .dlls, another important thing type of implementation mini-usb connector, etc etc. so you have to check more things with usb tmc receiever to be sure that is compatible with your device. Posting info like "2 differen units" doesn't mean anything, cause nobody can help you, if you didn't write more details about devices, platforms, etc. , so don't expect help, help people with more info, to get help!
