VM116/K8062 Not recognized by Windows 7

I have a VM116/K8062 USB DMX interface. It works fine on XP machines. Windows 7 machines do not recognize the device. I tried a 32 bit and a 64 bit machine, same result. In the device manager it says “Unknown device” and “Windows has stopped this device because it has reported problems. (Code 43)” Any suggestions? Thanks.

Please see this thread for possible help: viewtopic.php?f=3&t=7258
It is for other card K8055/VM110, but it has the same USB “core” as the K8062/VM116

Thanks for the link. I tried the easiest solution: A powered USB hub solved the problem! Thanks for the quick help!
