I just had the same issues with the ToupCam - which is the same camera. I tried both Altair's and Toupcam's drivers. I tried the Altair camera driver, WDM and various ASCOM drivers. All the drivers connected and produced an image.
I could sometimes get a dark pixel map to complete but when I set it going, (not guiding, just sampling), I had random bright frames and it repeatedly timed out (>15 seconds) during download, especially if anything else was happening at the same time. I think the WDM is one way to go - but for me I don't want to set half a dozen video parameters to produce a guide exposure. When I swapped it out for my Lodestar X2, everything was good.
I gave up in the end and just returned the camera to the dealer. I'm not an expert but it feels like there is something like bus contention with this camera/driver. I need reliability and simplicity over economy and bought a Superstar, which has similar sized pixels.
