The USB interface supports 3GPP TS 27.010 multiplexing, and may be used as the
primary AT-command interface.
Internally, the USBDP line is pulled up by a 1.5K resistor, in accordance with the USB
standard, to indicate that it's a full-speed capable device to the USB controller.
To implement successful applications using the GR64 USB interface, users should
familiarize themselves with the USB specification.

The maximum distance between the SIM card holder and the Wireless
CPU varies depending on the application implementation. SIM holders
placed too far away from the Wireless CPU may not meet the SIM
interface performance specification.
