3 Months After VR Launch - Any Better?

I’m a techy but can’t get it working. But I have weird situation.
I have VIVE (I no longer use) it’s downstairs. I have Quest (1)
I have used it to wifi from my downstairs computer to upstairs.
I have done this with virtual desktop. (works fairly well).

I have new i9 upstairs with FS2020 from MSFT store.
I have older i7 downstairs with FS2020 from STEAM.

I have only used VD to the downstairs computer with steam.
Must I still use steam?

Any way to quest(1) upstairs on new PC? I have tried the cable but it always says it’s USB 2.0. I know it’s not. Maybe it’s the cable? But I have the ANKER “C” cable that is said to work?

Maybe I need to bite the bullet and get the Oculus 75.00 cable?
If I have the cable so I still use VD? on location machine? Or will the wire to the upstairs PC work direct with MSFT STORE version of FS2020? Is steam required? (I’d prefer not to use steam vers).
LOVING FS2020 I’ve had ALL previous versions from early 80’s and was never THRILLED with any of them. I’m finally THRILLED. It’s real.
