No problem. I ran into this same rock on a Lenovo for months. Once I got TEST SIGNING enabled and got the vCOM drivers properly installed, my device had instant communication with my PC via USB connection/SP Flash Tool. Let me know. On my Viking Pro, I've had no problem with using the SP Flash Tool. I have a newer Viking Pro like yours.

Turns out the drivers were already signed, but I uninstalled them and they re-installed easily with Test Signing enabled. Still no luck. funny thing is, all my other android devices are recognized when I connect them in regular, recovery, or fastboot modes - even if only to say "driver not found." This? not even a blip in Device Manager...

Use Linux
My advice to anyone having trouble connecting your tablets, use a Linux distro (ie: Linux Mint, if you've never used Linux before, Ubuntu has a lot of support too). You don't have to install it, just use it from the USB. IF you're lucky enough to have a USB 3.x interface, whichever distro you choose will run fairly well from it. USB 2 will be a bit slow, but will still work.

There will be a few hoops to jump through, like setting up udev rules and such, but after that, everything just works. I was even able to use ADB on my Maven Pro, whereas, it just doesn't work with Windows...

Access via USB
On Windows 10 it is possible to access the device via USB. This was described by the creator of this post SmartmanVartan and can be found in his tutorial. There about a 5 second window when the device is turned on and plugged into the PC. Device manager is onscreen and the device will show up in the lisstings.
