I'm running ubuntu 18.04 and have the same problems with USB 3.0. The ONLY way to get it to work at all ever is to turn iommu off in the bios and use iommu=soft as kernel parameter (as is described as the "solution" on many forums) AND I need to have certain device plugged into USB and/or something else magical that I didn't pin point.
Anyway, once USB 3 works, it keeps working until I turn off a device (Valve Index headset), or rather when I quit steam, I get the following dmesg: [ 7211.963003] xhci_hcd 0000:04:00.0: xHCI host not responding to stop endpoint command.

After that those USB plugs are dead. I have no figured out how or even if it is possible to revive them without a reboot. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1313279 Title: xHCI host not responding to stop endpoint command Status in Linux: Unknown Status in linux package in Ubuntu: Confirmed Bug description: Description: Ubuntu 14.04 LTS Release: 14.04 Hardware: Intel NUC D34010WYK (Core i3 4010U) Memory: 4 gigabytes USD device: PCTV 292e DVB-T tuner I have 2 PCTV 292e DVB-T tuners connected to the system.
