Interesting that nobody seems to recognize the problem with the USB ports in any of the hypervisors. The USB Ports work perfectly in El Capitan. The issue is only within any of the hypervisors. I've been experiencing problems with capturing any USB device (drives or my scanner) only in the Hypervisor. I've tried it with Parallels 11 and Virtualbox which has exactly the same problem with USB devices. I saw that Fusion customers are experiencing the same issues as well. Since I've already spent the money on Parallels, I didn't want to purchase Fusion just to see that it doesn't work there as well. This looks like an Apple problem but until companies such as Parallels starts working with Apple to first acknowledge that there is a problem, there will be no fix.
After moving back to Yosemite and Parallels 10, the usb devices all work perfectly. However, with the amount of malware and hacking today, this is not recommended for security reasons.
It is the hypervisors that run windows which make the Mac useful other than Adobe CS that run natively on the Mac. This has been broken for some time now. With no fix in sight, there is no choice but to return to the PC so that I can get some work done.
