USB Broken after 11.5.3 to 11.5.4, 11.5.5 and 11.5.6 Updates

This post was originally published on this site

I have searched these forums carefully looking for a solution. I have tied several of the Solved items and some more than once. I am running macOS 10.15.7 with Fusion 11.5.3 and everything works great. In the past, I have tried updating to 11.5.4 & 11.5.5 and could never get the USB to work on my Windows 10 VM. I was notified of the 11.5.6 update and thought I would give it a try. Same problem again. As soon as I put Fusion 11.5.3 back, it works flawlessly. The thing that gets me is I am not doing anything special. I just need t plug the occasional USB Thumb drive into a USB port and read & write to the USB stick. Another thing I am trying to do I read and write configurations to a Whistler and/or Uniden scanner radios. Again, there is nothing special. You plug the USB into the USB port on the radio and Windows 10 simply sees it as a USB drive. Not rocket science. I don’t want to be rude but after reading some of the suggested fixes and trying to solve my problem I am asking myself how this kind of problem makes it past QA. This seems like a very common everyday need.


So, I am talking about the latest 11.5.6 update. I have all the devices set to “Ask what to do”. When I plug in any of these devices I am prompted to select Connect to Mac or Connect to Windows. I select Windows and most of the time I hear the Windows “happy sound” letting e know my device was connected. BUT, Windows Explorer does not see the newly attached thumb drive. If I wait just a few moments Windows gives me the disconnect “happy sound”…a few seconds later Windows again gives me the connected “happy sound”. This was after I put the suggested settings:


usb.generic.allowHID = “TRUE”

vusbcamera.passthrough = “TRUE”


in the config file located in /Library/Preferences/VMware Fusion/


I would really like to purchase the update to Fusion 12.x but I see people are reporting similar problems with USB there as well. I have spent hours looking for a solution and have found nothing. I have looked at a number of postings all having what sounds to be the same or similar to my issue. I have tried the solutions posted in the threads marked “Solved” and nothing. Hopefully, someone can offer some guidance that will help me out.
