USB disconnects all the time

[PeterZ]

Hi guys

Recently I started using USB for the first time on my system, I want to use a zigbee USB stick which doesn't go well at all.
The plan was to use a LXC for this but couldn't get it to work after a lot of trying I have discovered something strange.
In the BIOS, I have disabled USB 3.0 since this is advised.

This is a part of the systemlog (I have filtered lines containing USB and hub)

Anyone?

I have seen combinations of a motherboard and a USB device where the device would contiguously disconnect and connect. In my case, I suspect the cheap gamepad device to not fully adhere to USB standards and the motherboard to be unforgiving about this. Other devices worked fine and the gamepad worked on another system.
Try switching one or the other, or try a USB port connected to another controller (or add-in card)?
Can you try booting your system using a Linux LiveCD to see if this also happens without Proxmox?

Bumping an ancient thread here, but I have this exact problem, albeit with a different USB device. I have, as suggested, tried a Linux LiveCD on the same hardware. The USB device does not disconnect and reconnect as above using the LiveCD. That rules out a hardware problem, any ideas on what else to look at?

Currently using "Virtual Environment 6.4-15" and also experiencing this issue. Was ignorable when it just disconnected and reconnected the Mouse and Keyboard, but after setting up a UPS it drops the connection every 5 minutes, which makes monitoring impossible.
