Re: ZWO ASI 294 Dropped Frames

Folks
Thank you for continuing to try and help me. Some answers to questions.
The camera has been directly attached to the x3 USB Ports in turn ie not via a hub. 2 of the ports are directly attached to the Intel Motherboard, the third is attached via a Daughter board which sockets onto the mother board - the camera drops frames regardless of which USB connection is used.
I have used a USB 2.0 extender cable - no change. I have used a USB 3.0 4 port Hub on every USB port - no change.
I have attached a file showing the laptop with mouse only on the daughter USB, then Camera on the other two direct motherboard USB. I noticed when the camera is attached the tree view software shows two connections Port 18 or 17 (dependant on which USB connection I plug into) and Port 2 Generic USB Hub and further down the tree Port 1 ZWO ASI 294MC Pro Camera which is very confusing. The equivalent view on the AMD Laptop shows a simple direct connection to the AMD USB 3.0 eXtensible Host Controller 1.0 (Microsoft) not multiples.
In addition I have run the Microsft USB fault finder application and it reports the USB controller to be in a failed state - see attached.
Dell are bewildered. They have offered the following.
Replace the Motherboard with a brand new (not refurbished item. Replace the HDD, replace the SSD. Install a complete new Windows 10 instance. Then on a fresh unused HDD, SSD and Motherboard install Sharcap 3.1 and the ZWO drivers - test for dropped frames - if problem resolves Dell will close the case, if problem persists Dell consider the issue to be ZWO/Sharcap conflict with Intel system.
They will conduct this work next week.
If anybody has any advice before pursuing this drastic path I would be very grateful.
Thankyou and regards
Ian
P.S I got some great captures of M16 and M20 the other night on the ...... AMD Laptop !
