3.10.2.2. USB
The MSM6250A device contains a Universal Serial Bus (USB) interface to provide an efficient interconnect
between the mobile phone and a personal computer (PC). The USB interface of the MSM6250A was
designed to comply with the definition of a peripheral as specified in USB Specification, Revision 1.1.
Therefore, by definition, the USB interface is also compliant as a peripheral with the USB Specification,
Revision 2.0. The USB Specification Revision 1.1 defines two speeds of operation, namely low-speed (1.5
Mbps) and full-speed (12 Mbps), both of which are supported by the MSM6250A.
U880’s USB interface uses the PM6650-2 internal logic for USB Transceiver.
