I'm running a guest Mojave(macOS 10.14.6 on Catalina macOS 10.15.3, with Parallels V. 15.1.2. I was checking on USB attached devices and have accidentally caused a problem somehow. I had had a printer connected successfully (via USB) to my Mac, but now every few minutes Parallels keeps asking me where to connect it. I keep telling it the Mac, but it doesn't remember and asks again... Help!
