I'm trying out Virtualhere. Nothing fancy. Two Windows 11 computers in the same building, on the same network. Nothing special about the computers.
I plug in a SanDisk USB flash drive on the server and I'm able to use it on the client as expected. All good so far.
BUT, on the client computer, when I right-click on the device in the Virtualhere client and click the option to stop using the device, things go haywire on the server computer. It disables everything USB, AND kills bluetooth. The bluetooth device completely disappears from Device Manager. I have to reboot the server computer 2 or 3 times to get everything working again and get bluetooth back. I use a bluetooth mouse on the server computer, and the mouse stops working. That's how I noticed that even bluetooth gets killed.
Here is the server log.

Can you stop and exit the virtualhere server then download and run this instead and tell me if this server works better for you

On an extra note, I also tried the server version from the Windows store and it did the same thing.
.
Ok not sure sorry. I dont think its compatible
I tested with some other USB…
I tested with some other USB drives. It's something with that specific model of USB drive. I tried other models of USB flash drive and they worked fine. I also have several different drives of the one that fails, and they all fail in the same way.
But the ones that fail are still just a typical USB flash drive. What would be special/different about these? They are USB 3.0 flash drives if that makes any difference. (The other drives I tested that don't fail are all USB 2.0 drives.) These USB 3.0 drives DO work on connection. I can connect to the drive from the client, and I can open the drive in File Explorer on the client and view files, copy files off, and copy files to the USB drive. That all works fine. It's only when I go to "Stop using this drive" that it then causes the issue.
.
I suspect it might be a mode switch issue inside the disk.
Some USB 3 disks support UASP. Virtualhere server on windows wont support this so it tries to switch it to standard BOS disk mode.
(Virtualhere client on windows does support UASP drives together with Virtualhere Server on Linux)
I suspect if you plug the drive first into a USB 2 port (or USB 2) hub and use it via virtualhere it would work ok.
