Which has two USB chips on it: one is SL811HS and another is ISP1362. The SL811HS is an Embedded USB Host/Slave Controller capable of communicating in either full speed (12 Mbps) or low-speed (1.5 Mbps). SL811HS can work in two modes鈥攈ost or slave, but is not On The Go (OTG). Data sheet can be found at <a href="http://www.cypress.com/portal/server.pt?space=CommunityPage&control=SetCommunity&CommunityID=209&PageID=259&fid=10&rpn=SL811HS" class="urlextern" title="http://www.cypress.com/portal/server.pt?space=CommunityPage&control=SetCommunity&CommunityID=209&PageID=259&fid=10&rpn=SL811HS" rel="nofollow">here</a>.</p><p>The Philips ISP1362 which is a single-chip Universal Serial Bus (USB) On-The-Go (OTG) controller integrated with an Slave Host Controller. It has two USB ports: port 1 and port 2. Port 1 can be hardware configured to function as a downstream port, an upstream port or an OTG port whereas port 2 can only be used as a downstream port. The OTG port can switch roles from host to peripheral, or from peripheral to host. The OTG port can become a host through the Host Negotiation Protocol (HNP) as specified in the OTG supplement. You can find more information <a href="http://www.semiconductors.philips.com/pip/ISP1362EE.html" class="urlextern" title="http://www.semiconductors.philips.com/pip/ISP1362EE.html" rel="nofollow">here</a>.</p><p>You can get the USB card’s schematic and PCM layout <a href="http://blackfin.uclinux.org/frs/?group_id=7&release_id=262" class="urlextern" title="http://blackfin.uclinux.org/frs/?group_id=7&release_id=262" rel="nofollow">here</a>.</p><p></p></div><!-- SECTION [76-1434] --><h2><a name="jumpers_setting_on_usb_add-on_card" id="jumpers_setting_on_usb_add-on_card">Jumpers setting on USB Add-on Card</a></h2><div class="level2"><p>Set J3 to choose a PF pin as interrupt for ISP1362.
