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.
1. Re: Ported number from Straight Talk to Verizon--how long does it take? Verizon Wireless Customer Support Sep 19, 2014 3:14 PM (in response to jesse_dylan) jesse_dylan, Help has arrived! When porting a mobile number from one carrier to another, the process can take up to 72 hours to complete. If there is a delay in the process it can possibly take longer. Once the port is completed you should receive a notification. To help sync the existing number on your new phone try rebooting it.
