I've encountered a very strange problem. When I attach the LightCrafter 3000 to USB port, it always takes like 5 minutes until the software can connect to the device. Once it is recognized and usable, some programs seem to hang unexpectedly: Cannot close task manager, Visual Studio getting stuck unpredictably, sometime I cant even open network connection manager and sound devices. Everything becomes normal when I detach the LightCrafter. Im currently using Windows 8.1 64bits. I think the problem may be coming from the RNDIS driver, I have it updated but it all still same. Please help me out. Thank you!
