Hi,

I have a K8055 working on my pc and all is correct for my application and demo software. But when I switch off the Pc and reboot it next time, if my K8055 is connected to an USB port, when the pc boots, the output Led 8 is flashing momentanly for 1 or 2 seconds and get permanently on. I can’t initialize my k8055.
If I disconnect and reconnect the USB cable, the led8 flashes momentanly and after all is ok and I can use my K8055 card without problem…
Do you have a solution to activate the K8055 correctly when I boot the PC?
I am using XP SP2 version.
Many thanks.

The first two flashes of the LED LD8 indicate that the PIC microcontroller software has started properly. On the third flash the LD8 stays on if the USB connection is not initialized properly. This seems to be the case with your PC. The only solution in this case seems to be to unplug and replug the USB cable - sorry.
