What does ttyUSB mean? Sometimes, the embedded microcontroller does not come with a hardware USB interface. While it is possible to use a software-only USB stack, the additional constraints put onto the CPU and the usually small storage size often lead board designers to include a dedicated UART to USB bridge.
Because of a busy weekend I didn't really follow up other than via emails and this still hasn't been resolved. The consistent word from them was that porting a number sometimes takes 24 to 48 hours.. I spoke to a rep by phone today who promised it would be done within 2 to 4 hours.. It wasn't.
How ever it almost always never takes as long as they say. It only took 1 1/2 hours for my number to be transferred from t-mobile and my brothers took 1 hour to transfer from verizon. So imagine that if you are just transferring numbers from another virgin mobile phone it should be alot faster.
