USB PCIe Card Passthrough, glitching and instability on W10 Guest

[matt91]

Hi,

I'm new to Proxmox having only installed it in the last week for my combined server/workstation build (AMD Epyc 7282, Asrock ROMED8-2T, Nvidia GTX 1660 passthrough, Silverstone ECU05 ASMedia ASM1142 PCIe USB card passthrough).

I have a Windows 10 guest I have passed through the GPU and USB controller to. The GPU passthrough is working perfectly, however I have been getting random glitches on my USB devices (keyboard/mouse freezing, USB drive copying intermittently dropping to 0KB/s, webcam artefacts and sound artefacts). I have tried unplugging USB devices and hubs and have even replaced the USB controller (previous one was a a generic Amazon purchase, with a different chip).

The only error I have in the Windows event log is BTHUSB, Event 5 "The Bluetooth driver expected an HCI event with a certain size but did not receive it.". I removed the Bluetooth dongle and rebooted, which stops this error, but doesn't fix the issue with other devices.

Has anybody had similar issues to this and can point me in the direction of a fix?

I initially tried passing through the integrated AMD USB controller, however this caused the whole server to crash. I read this is a known issue, hence trying a USB card.

I am very happy with Proxmox otherwise, and does everything I want. Once this issue is sorted I'll be purchasing a subscription.

If you require extra information/logs, please let me know which you want.

Thanks, Matt.

Hello,

since the latest update I'm experiencing the same Problems. I also have my GPU and a USB 3.0 PCIE on Passtrough.

Since the update I have Input lags of about 100ms every 2 or 3 seconds, the machine performance and gpu performance seems ok.

Is there any solution on this problem?

Thx in advance

The input lags are exactly what I'm experiencing. I installed and updated the packages immediately, so don't know whether this was an issue before.

Hi,

is there any hint on the horizon or are we lost with the performance issue.
I shouldn't have updated the server - never change a running system... ;-)

Here is my m output

Did you find a solution? It was my "main" Desktop and is now not really usable...

Hi, I'm using it as my primary desktop too. I've had to revert to passing individual USB devices through, which makes it all workable. Luckily I only have 5 plugged in currently, which is the limit for this method. I'd like for this to be resolved, I'm crossing my fingers it's resolved in a future update.

If anybody has any ideas it would be much appreciated, Thanks

Maybe it hast something to do with the kernel. This external thread is 2 months old describing similar problems. (except that my gpu passtrough is working normally)

Ok, it seems that my problem is slightly differnt to yours. If changed now my USB Devices to the internal Host Controller and I experience the same stuttering. (enabled 3.0 btw) So my input/output lag is independent from the pci device.

Very annoying. I want my old system back...
