Strange that the power LED is blinking.
It seems that the USB voltage (+5V) from the PC is interrupted periodically. How often this happens?

When LD8 stay’s ON, there is a problem accessing or running the HID driver from windows, please be sure that you have admin access during installation and running of your K8055
Please read also the forum rules, always start a toppic with the project nr (K8055???) !!!
