you mean from a standard usb port/header on the mobo to a pcie slot adapter? no go.
the usb cables in risers just carry the pcie signals from the slot to the adapter. they do not use the usb protocol; the usb cables just happen to have enough individual wires and bandwidth to work so are convenient to use.
you could try a pcie port multiplier but not sure how well you could fit that in there.

Thank you for the information. Yes, that was part of my question "Can the standard USBs interface a GPU." Answer, No, Thank you.
Second part of the question. Does anyone have experience with these devices:
PCI-e Express 1X to 3 Port 1X Switch Multiplier HUB Riser Card +USB Cable 1PC

I have these on a test rig (MEGATRON): 7 x R7-370s, Win 10, ASrock H81 Pro BTC mobo, 8GB RAM, 120Gb SSD.... working like a charm. The card goes into the last slot and connects to GPU 6 and 7.
Its currently mining ZEC - fast and furious, with CZM v5, runs cool
Would you think that this would lend the opportunity to have a 8+ GPU RIG?
Yes.... but after talking to many members.... anything beyond 8 cards need Linux OR Windows Advanced Server with several registry hacks and special drivers... gets complicated.
Also you need bigger PSU.
Someone in Ethereum forum did 8 cards on Ubuntu 14.04.
If you want multi multi GPU, search for this dude on Claymore Eth thread, who did I think 18 x GPUs on Linux and Claymore had to add feature to allow more than 12 GPUs. He used a PCI extension daughter board - usually used for deep learning machines -- but that is super expensive and not practical for mining
