PC can't boot with K8055 plugged

Hello,

my system is not able to boot, if a USB port is linked with my K8055 board. The monitor is not initialized so I’m not able to look up any error messages, while at the board LD8 is illuminated permanently. If I unplug it, the computer begins to boot properly. Does anybody know why this happens and how I can fix that problem without plugging all the time?

Otherwise the board is working all correctly. I don’t understand that… :confused:

It seems that your PC is trying to boot from USB.
You may avoid this by changing the BIOS setting.
