Think we're not 100% out of the woods with Parallels 17 USB issues just yet. Yeah, it's now recognising things, but there are other side effects that would not necessarily be readily apparent. Here are the observations:
1. In all VMs (Android 9, Linux FC35, Win11) the trackpad mouse erratically zips across the screen without warning. It often disappears completely after clicking in a terminal window.
2. I do related development for a USB-based software defined radio on macOS, Linux (FC35), and Win11. On the Linux and Win11 VMs the radio erratically loses, then immediately regains sync, as witnessed by annoying audio dropouts and redisplay of specific station information.
3. I have three external drives, one of which is a time machine drive. Often when a Parallels Linux or Win11 VM is running, the VM erratically attempts to capture the drive, causing macOS to think all three drives were disconnected without properly ejecting. God help me if a time-machine backup was in progress when this happens. Even worse, this kicks off a seemingly never-ending set of mds and Spotlight processes that are required for just-connected time-machine drives and can't be turned off.
All of these are related by USB (trackpad/keyboard is internally connected on the USB bus) and only occur when a Parallels VM is running. My hunch is that Parallels is doing some kind of periodic USB polling that is interfering with native macOS USB operations and/or communications.
My system is:
Machine: MacBook Pro (Retina, 15-inch, Early 2013)
Processor: 2.7 GHz Quad-Core Intel Core i7
Memory: 16 GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000 1536 MB
OS: macOS Catalina 10.15.7, up to date with all available security patches.
Let me know if reports need to be generated for each VM and each symptom... but that seems like a lot of stuff.
