Hi,

I did add the OnDeviceArrived handler to my MainForm and indeed if i run my program and plugin the K8055 it is recognized and functioning.

But if i run my program while the card is already plugged in i cannot get it to initialize. The method NumBoardsPresent always returns 0 and the K8055Board.IsPresent remains False on all board addresses. This means i always need to unplug and plug in again as the card normally is not unplugged. 

Surely there must be another way?

Jack.
