<!-- SC_OFF --><div class="md"><p>Hi, I have 2 Arch linux computers with newer Intel CPUs which I recently updated all packages, including the kernel (to 5.14 I believe). Now all usb ports on both computers are broken, devices plugged into them do not even receive power. USB devices work on those computers when in BIOS or booted into Windows (one of them is dual boot).</p> <p>I have a 3rd Arch linux computer, a very old embedded AMD system. It is running the latest packages and kernel without issue.</p> <p>Troubleshooting this is nearly impossible since I cannot use keyboard or mouse, and I did not have ssh enabled on either of them. This problem is also present on the latest live USB, however I was able to get an older (september) live usb working albeit with usb error messages. From that live usb I chrooted into one of the machines and installed the LTS kernel, however that does not appear to solve the issue either.</p> <p>Specs:</p> <p>Computer 1:</p> <p>Intel i9-9900T</p> <p>32GB RAM</p> <p>nvme 500gb primary ssd</p> <p>Computer 2:</p> <p>Intel i9-???? (forgot and cannot boot)</p> <p>64GB RAM</p> <p>nvme 2tb primary ssd</p> <p>Computer 3:</p> <p>Old embedded AMD 1.0GHz Athlon</p> <p>16GB RAM</p> <p>​</p> <p>Some of the errors I am receiving:</p> <pre><code>xhci_hcd 0000:00:14.0: xhci host controller not responding, assume dead xhci_hcd 0000:00:14.0: HC died, cleaning up usb 1-3.1: device not accepting address 13, error -108 usb 1-3-port1: couldn't allocate usb device </code></pre> <p>​</p> <p>Edit: I have resolved the problem. I had a webcam on the KVM which apparently malfunctioned. For whatever reason this caused serious problems with the usb handling in the newer kernel on these newer Intel motherboards. After removing the webcam and rebooting, usb works as expected and there are no more dmesg errors.</p> </div><!-- SC_ON -->   submitted by   <a href="https://www.reddit.com/user/archthrowaway123456"> /u/archthrowaway123456 </a> <br/> <span><a href="https://www.reddit.com/r/archlinux/comments/r5t67e/multiple_arch_computers_all_usb_ports_broken/">[link]</a></span>   <span><a href="https://www.reddit.com/r/archlinux/comments/r5t67e/multiple_arch_computers_all_usb_ports_broken/">[comments]</a></span> |
