Really wierd error - no USB2 devices not being found whilst USB3 devices are

[g__day]

So I try to practice more imaging today,


Realise I must have banged a USB 3 cable - bummer - so I am down one of my three ZWO cameras (ASI071MC-c Pro) but I swap over the USB 3 data cable coming into my ASI0120MM-s and the 71MC is detected straight away so I think it will only take a day or two to order in a new 2m USB 3 cable so I will guide off my spare guide camera - a QHY5L-II.


But for the first time in ages it isn't detected? Then I notice my ZWO filter wheel connected to my ASI1600MM-c isn't detected, nor is one of two USB2 data keys in 2 different hubs, nor is my TemperHum Gold which always works.


I have 4 USB3 hubs (two dual Mbeat USB3 /2 hubs) and two by other brands. None of my USB2 astro cameras connected to USB2 or USB3 hubs work at the moment (USB device error under Windows 10 - device failed to set memory).


I haven't ever seen that error before - I tried moving devices around, trying different cables and different hubs and different external power supplies to the USB3 hubs. I tried uninstalling the 3-4 unrecognised devices and scanning for changed hardware. I tried re-downloading the latest drivers.


I scanned for hidden USB3 devices...


I can't figure what this weird error is. Yesterday all my gear was working perfectly. Astro lab PC didn't shutdown overnight, no warnings at all until tonight when I decided to keep imaging M83.


Any ideas folks? I will try my non detecting gear on a PC inside the house - unless 5 separate cables (4 USB 3 and 1 USB 2) failed, or 4 USB3 and 1 USB2 hubs failed only for USB2 devices I am at a loss for what just happened and how to simply fix it.


I wonder if a Windows USB2 stack got corrupted somehow and if this can be detected and restored - cause that's what seems to be the common denominator at the moment.


Many thanks,


Matthew

Update 2.0 - PC failed to boot after 10 minutes - MS Error DPC ... arggh!

Disconnected an old HD (third such in same PC) and re-connected my boot SSD from an add in card to direct into the motherboard - then the PC booted first thing.

Once the PC re-booted this way the majority of my USB2 hubs and devices reconnected (minus the two on the back of my astro cameras - one of which connects the filter wheel). The coin dropped it was the hubs on the back of my ASI1600MM-c and ASI071MC-0c Pro that had failed to initiate! But at least now I have a guide camera and a filter wheel back in action (once I swapped cables and connected it directly to a handy USB2 hub).

So I try and run Troubleshoot and long story short find this release of Windows 10 has removed access to USB / hardware trouble shooter... arrgh! Then I find from a Administrator CMD I can run "msdt.exe -id DeviceDiagnostic" which brings back the troubleshooter, but it doesn't manage to fix the problem. Another day - more fun with Windows!

The good news with this issue you are having is it has been tracked down to a known virus.
The bad news is the virus is called Windows 10.


Couple of links may help.

Look for 'COM Name Arbiter Setter Tool' halfway down in above web page and download to clear USB ports.
