> [ Original Description ]
> 
> My raspberry pi 4 running Ubuntu 20.04 server is constantly having trouble the the usb controller.
> I have 2 externally powered USB hubs connected that have a few HDDs plugged in.
> 
> After a seemingly random amount of time (between 1 minute and 2 days) the usb controller will crash completely. No USB devices are detected anymore after that, i have to reboot the system.
> 
> I have tried:
> * Providing a lot of cooling (metal case + desktop size fan)
> * Switching the USB Hubs to a different brand
> * Switching the power supply of the USB hubs
> * Switching the power supply of the raspberry
> 
> Nothing helped, so i concluded that this probably is a kernel bug. I think the USB controller should not crash at the very least.
> 
> I've attached my dmesg.
