i belive (looking through
archive.org),
kryoflux.com
used to sell a usb
adapter for 5.25" floppy drives. their current web page has the sales tab
replaced by "we are temporarily restructuring", but i seem to recall a
couple years ago not selling anything either. going back further I think I
saw a usb controller for 5.25 inch drives, though not 8 inch, sadly.
Anybody have any news on whether they will actually come back?
FWIW: If you have a Mac, the Apple Sauce+ FDC does the same thing as the Kryoflux.

It can do standard reads of _many_ formats, as well as a complete Flux read of the disk.
Hook up any type of drive and read it in over USB. Besides my Apple 3.5" external,
I've done PC
Teac 3.5" drive and 5.25" drives. I still have to get my Apple 5.25" drive
out of storage).
The documentation says he has tested 8" drives, with some suggestions for the Shugart
50 pin
adapter down to PC type cable.

The software support is excellent (but Mac only as I mentioned), and
I'm amazed at the # of odd formats he supports.
Unfortunately the hardware is currently sold out. But per their
discord discussion, the guy behind it is planning on another run of
his hardware at some point in time. Just be patient and wait out the time it will take.
