I have an open dmx usb (actually I built it) that is known to work perfectly fine on my desktop computer at home. I plugged it in and installed the drivers which I downloaded from the enttec site. Everything works (I use Magicq). I tried this today with my laptop. I plugged it in, installed the enttec drivers, everything's shiny. However, I unplugged it and plugged it back in. Windows immediately claimed to know nothing of the device and requested permission to go online and find drivers (I denied it.). It's like windows dumped the drivers when I unplugged the usb-dmx adapter. I can make it work again by running the enttec driver installer. This only happens on my laptop. Any thoughts?
