This may help... fixing a different problem I found out that there other files in the Library folder that need removing (as well as uninstalling Parallels Tools) in order to get a nice clean Parallels Desktop when reinstalling.I've solved it uninstalling Parallels, deleting /Library/Preferencies/Parallels, reinstall 16.1.2 from scratch, after activation I've loaded the VM and now all usb devices works, don't know if it's a bug related to upgraded versions.
The ones I also deleted are:
- ~/Library
- ~/Library/Application Support
- ~/Library/Application Scripts
- ~/Library/Caches
- ~/Library/Cookies
- ~/Library/Preferences
- ~/Library/Saved Application State
- ~/Library/Containers
- ~/Library/Group Containers
- ~/Library/Application Support/CrashReporter
- ~/Library/WebKit
- /Library
- /Library/Preferences
- /Users/Shared
- /private/var/db
- /private/var
