Is there a USB B to USB C Adapter

Try Ghent Audio. You can put the USB connector of choice on both ends. 

Thanks lanx0003 . As I mentioned last year, I sold the cable and bought a USB A to USB C Cable, an AQ Cinnamon. I had been hoping to find a USB B to USB C adapter so I could still use the cable I had. AQ made numerous USB connector adapters, but not a USB B to USB C , so therefore the new cable, which has been working great.

did get a quick response from AQ that they do not make a B to C, only an A to C...at that point I decided on a new cable...thanks to all...

agree carlsbad2...

Sell your cable and buy the right cable.  the adapter will never be of the quality of the rest of your cable system.

i use b to c all the time with my printers

mine is A to B, and yes I was thinking to sell mine and purchase an A to C

You didn't say what the other end of your existing cable is (A?) but I suspect that a new A to C cable (or whatever to C) would be the best solution, even if you don't buy a fancy one. If you use an adapter, you're just introducing another set of connections into the loop with the associated extra resistance and a higher chance of problems.

Thanks but those are A to C

Not these?
