CB2-PIPE
CompactPCI   5-Port USB 2.0 Host Controller


The CB2-PIPE is a 5-port USB2.0 host controller. The 3U CompactPCI® board complies with the Universal Serial Bus Specification Revision 2.0 and Open Host Controller Interface (OHCI) Specification for full-/low-speed signalling and the Intel Enhanced Host Controller Interface (EHCI) Specification for high-speed data transfers. All downstream facing ports can handle high-speed (480Mbps), full-speed (12Mbps), and low-speed (1.5Mbps) transaction.

In addition, the CB2-PIPE optionally can be equipped with an on-board Flash disk drive.



All USB power lines are protected against over-current and short circuit conditions. Four of five USB ports are accessible from the front panel.

The fifth USB connector is situated on-board for system internal usage (as an alternate to the Flash drive).

All popular OS come with suitable drivers for the CB2-PIPE. In addition, any recent BIOS offers boot via OHCI. In order to boot in high-speed mode from a drive attached to the CB2-PIPE, the BIOS must also handle EHCI based data transfer.
