I still think your camera is working just fine. I'd put a 50mm DSLR lens on it and take some pictures inside. I looked at the specs for a QHY10 and see its using a progressive ccd from Sony, this means it should take images down to .001 second. Set INDI gain to 1 and see what you get. If it keeps coming out all white, try setting the offset down.
At the time the QHY10 was being developed, USB2.0 was the standard for interface transfer speed. The camera specs call for a 1x1 image to download in 18 seconds. If its possible on your INDI control panel, try experimenting with the USB polling times. The setting is located under the Options tab. The buffer settings should go, hand in hand, with the image binning. A binning of 1x1, 2x2, and 4x4 should work best with a buffer of 4096, 2048, and 512 respectively. The setting can range down to 10 and up to seconds.
If you are using a Pi or powered USB hub which allows selection of USB2.0 or USB3.0 ports, experiment with different transfer speeds and cables. Delays from outside noise and cable 'ringing' all come into how fast a camera can transfer.
Lastly, expecting a stream of 10meg images to transfer in 1 second intervals... is well.... going to be a challenge. If they are binned down to 4x4 and the buffer size matches the USB transfer speed, well....
