USB Interfaces

The CP308 supports eight USB 2.0 ports: two on front I/O, three on the high-speed I/O
extension connector J12, two on the rear I/O CompactPCI connector J2, and one on the USB
2.0 NAND Flash connector J14. On the USB 2.0 rear I/O ports, it is strongly recommended to
use a cable below 3 meters in length for USB 2.0 devices. All eight ports are high-speed, full-
speed, and low-speed capable. Hi-speed USB 2.0 allows data transfers of up to 480 Mb/s.
One USB peripheral may be connected to each port. For connecting more USB devices to the
CP308 than there are available ports, an external USB hub is required.
