3.10.2.3 USB
The MSM6250 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
MSM6250 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
MSM6250. U880's USB interface uses the PM6650 internal logic for USB Transceiver.
