Hi, I just put together a K8055 USB experiment Interface Board, but have some problems connecting it to my pc.
When I connect it with a USB cable the power led (11) lights up, and ld8 flashes, but after that, ld9 (PWM1) also briefly lights up. Then both ld8 and ld9 go off and LD11 stays neatly on.
My computer briefly says it found a K8055 USB device, than changes to HID-device found, and ends up saying there was a problem installing the device. Your hardware might not function properly. When I try to connect it through the demo software, the card can’t be found. I tried all possible port combinations (both in the software and on the board). Nothing works.
Does anyone have any ideas or advise on what might might be wrong or where I should look to diagnose?
Thanks in advance!
