QHY colour filter wheel fault

I have an ongoing problem with QHY filter wheel, it will not select filters 2 or 3 when SGP calls for it. The wheel does select 1, 4, & 5 as commanded. I spoke with the supplier (Cyclops Optics) and they suggested deleting and reinstalling the ASCOM driver, and when that did not work they provided a utility that runs under Windows to communicate direct to the wheel via COM3 and that does work but obviously cannot be ordered through SGP. Cyclops have washed their hands of the problem, being that the wheel works driven by their utility.
So right now i cannot select filters through SGP sequence, but that had worked perfectly for over a year. No changes have been made to SGP, or ASCOM platform during this time.
Any ideas, its driving me crazy?

Hi I have had similar problems with one of my wheels. I fixed it by slightly loosening the screws around the perimeter must have been stressing the center bearing. Might not work but worth a try.
Clear skies Ken.

Thanks Ken. I think i have got it fixed now. I did a test with the wheel plugged durectly into my laptop, bypassing the hub and it worked. So i swapped out the cable, and plugged it through another USB port on my hub and and its working again.
