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.
You will need to wait until 24 hours after you have ported your phone number, then you will need to call Straight Talk and see why it is taking so long. Source(s): Tracfone/Net10 customer for 12 years. Straight Talk is a division of Tracfone wireless.
