Third.
I upgraded my OS partly under the specific verbiage "not fully optimized" meaning that /functionality/ would be retained and new features would not be granted, but I might have to sacrifice some speed in order to stay at version 10. As you quite correctly put it, there is a BIG difference between "not fully optimized" and "not working." I have a Fujitsu fi-7160 scanner that HAS to run in Windows. Now I am completely unable to scan until either Parallels 10 is patched or somebody wants to placate me with a Parallels 11 upgrade for free. (Your call, but one of these should be forthcoming. I paid money for a working piece of software, and USB hardware support is VERY BASIC functionality for this software suite.)
We cannot be expected to hold back a single generation upgrade based on Parallels' compatibility. It has been less than a year since I purchased version 10! If we were talking about 3 or 4 generations difference, I could understand a desire to break with compatibility of the older Parallels versions.
I am happy to provide log dumps or whatever else you feel would help you resolve this, but it's definitely broken.
EDIT: As an addendum to this, and for anyone else experiencing my symptoms: I was finally able to get the scanner to connect by disconnecting and reconnecting it several times. I also installed the recommended USB3.0 driver (designed for Win7, no compatibility listed for newer versions) in Windows 8.2 for good measure. Eventually it showed up under Device Manager connected to the USB 3.0 root hub. NB: I have USB 3.0 support ENABLED for the VM. The device IS USB 3.0 compatible.
