In Win7 I can get mine working under ASCOM, but it causes conflicts with my computers video drivers. My screen dims and won't brighten again. I've had the blue screen of death last time I tried, so won't be trying this again in a hurry
Can't get the XP machine to recognise it at all.
So I'm back to using my SPC900 and GPUSB.
I am assuming that it was a Windoze driver update that's caused it.
