Make sure you have the USB as an active boot device in BIOS, for XS7 if you arent upgrading, you need a 32GB USB drive at minimum. Just install and go.
Nothing special required.

I have a workstation (Dell T3500) that runs XS7 now, and it will only boot from the rear USB ports.
Double check the BIOS boot options maybe.

You need at least 46GB to install fresh. Try a 64GB stick.
Otherwise it will not show up on the install screen.
Or are you upgrading directly from 6.5 on USB? I was a little confused by your post.

Yeah I thought I recalled someone saying that fresh installs now required the use of a 64 GB stick/card.

That was probably me.
Don't you remember your trip out to the store to pick up a USB stick?

Did they give a reason?
-
Yeah because the lack of trim support will slow the disk down a lot. And lack or wear leveling.

That makes some weird assumptions..... like that speed is relevant and that you will have writes sent to the USB stick. So based on that reasoning, I think that it is a false recommendation. It's the same as all the recommendations ever... don't run Xen (or anything) from USB unless you make it non-writing. Or at least non-writing for things like logs.
So given that they explained why and it obviously doesn't apply. We can safely take that as a null recommendation.
