Finished building K8055, checked everything on board very carefully. Installed Demo program on XP system. When I connect K8055 the power LED turns on and LED 8 flashes briefly then stays on. The demo program claims that the K8055 cannot be found. Have tried K8055 set for card 0 thru 3. Also tried it on a Win2K system, same results. I have checked using usbview and the K8055 does not show up on the device list. I have not copied any dll files to system32 yet. I assume that installing the demo program puts everything that is needed to run the demo into the host computer.
Found the problem. R35 was open so the host couldn’t even determine the device USB speed. Fixed and everything now OK.
