This is with a new 2600MC camera; in both SharpCap and ASI Studio Live View. I can see exposures of up to about 4 seconds; longer and I get a disconnect message in the app and hear Windows do a disconnect/connect. This happens 100% of the time, making the camera kind of useless. Latest ASCOM and drivers; multiple USB cables used.
I've seen a bunch of posts like this elsewhere, but I haven't seen any definitive answer. Any thoughs or pointers?
