Hi!

 

I've been having problems with my USB devices disconnecting at random intervals, from a few minutes to a few days.

No amount of my googling has been able to solve this problem. This has happened on multiple installs of both Windows 10 and Windows 8.1 and in multiple storage configurations.

I'm able to get the devices back by manually running "virsh attach-device Windows <device>.xml".

 

Any help would be appreciated, thanks! 

 

My Hardware is as follows:

• Supermicro X10SLM+-F
  
• Samsung M391B1G73QH0-YK0 RAM
  
• Intel Xeon E3 1231 V3
  
• ServeRAID M1015
  
• R9 290 DirectCU II

I know this isn't a long-term solution but there is a nifty usb hot plug plugin. Might be a little more easy than your current manual commands:

Were you ever able to find a solution to this?  For I'm seeing this too using the hotplug as a workaround but have to use a laptop to do it since my mouse and keyboard will just randomly disconnect sometimes on my passthrough VM I use as my primary workstation?
