3.13.2.3 USB
The MSM6280 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
MSM6280 was designed to comply with the definition of a peripheral as specified in USB Specification,
Revision 2.0.
The USB 2.0 specification requires hosts such as PCs to support all three USB speeds, namely low-
speed (1.5 Mbps), full-speed (12 Mbps) and hi-speed (480 Mbps). The USB 2.0 specification allows
peripherals to support any one or more of these speeds.
KT610’s USB interface uses the PM6658 internal logic for USB Transceiver.
