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.
We do our best to complete this process as quickly as possible, however the port process can take 24-48 business hours to complete. 1  Your current provider generally will respond promptly, but officially do have up to 72 hours to release your number to us. We cannot control this timeline. There will be a period of time where both your old phone and Affinity Cellular phone will be without service during the port process.
