Well, what an interesting plot twist - turns out my thought-to-be useless efforts to set up a VM to get around my degrading fakeraid controller wasn’t so useless after all.
As a call-center agent I’m forced into home office - oh, btw, before you get the wrong picture of me: I’m not one of those fishy Idians (no offense) working in a scam-center - but I’m working for the big Shell oil company, which started an offspring company in the energy sector - so, I’m doin honest work.
Our IT department specifically required Win10 for the OS - although I can’t see why as we using Citrix anyway - which, as the name and history according to wikipedia suggest - should also have a unix client available. Anyway … nevermind.
So, as I had to get this working quickly, I already got the VM game ready, I now looked for a way to connect my audio interface to it. As I hadn’t time to tinker around a lot I’ve gone the quick and dirty way to use the usb redirect option. Overall it does work very well - but for some reason this very device keeps dropping out every now and then and reconnects itself after a few seconds. So far I got lucky to not have it happen during an active customer call - but I sense it will happen sooner or later. From asking google it seems like using this feature set to usb 3 can lead to some issues, as only usb 2 mode was tested enough so far. So, I tried to set the usb to usb 2 - but this causes even more problems as using the default usb 3 mode. I also didn’t had time yet to try to use vfio and 1-to-1 passthru as with my gpu, but will try that over the weekend.
Did any of you experienced such weird behaviour before?
I have a few thoughts about this problem, but due to time restrictions I wasn’t able to test any of them yet.
As my motherboard does have a few different usb root hubs I already tried changing around the connection to a different one - but the problem persists - so I would guess the root hub isn’t the issue here. As my keyboard and mouse don’t show that issue I even tried switching them around - but still no fix. I even tried to connect it to the physical usb3 root hub on the board - but that made the issue even slightly worse than better.
The next option I’ll try over the weekend is to set the audio interface to vfio and use passthru - if this works at all.
As I’m not experienced enough yet to tinker around with the bare XML or try to start the VM via command line I use the virt-manager gui. So, although it may be an option to go the low-level way I’m lack a lot of experience and can’T afford to get lost during testing to not have a working vm at all, as I require it for work.
Maybe some of you has some ideas if mine fail.
