https://bugzilla.kernel.org/show_bug.cgi?id=216497 Bug ID: 216497 Summary: USB connections through thunderbolt dock broken Product: Drivers Version: 2.5 Kernel Version: 5.19.9-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 15 Sep 2022 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: jhnmlkvch9@xxxxxxxxx Regression: No Created attachment 301819 --> https://bugzilla.kernel.org/attachment.cgi?id=301819&action=edit dmesg log for thunderbolt dock re-plug After updating to kernel v5.19.9-arch1-1, usb ports on HP Thunderbolt Dock G2 stopped working. dmesg is getting flooded with the message: xhci_hcd 0000:30:00.0: Error while assigning device slot ID xhci_hcd 0000:30:00.0: Max number of devices this xHCI host supports is 64. usb usb6-port1: couldn't allocate usb_device Obviously I don't have 64+ devices connected. Strangely, if I boot with the thunderbolt dock connected, everything works fine. Unplugging and re-plugging the dock again results in unrecognized usb. I'm attaching the part of dmesg where I unplug and re-plug the thunderbolt dock. Note that all usb devices that are connected are correctly enumerated while unplugging. Rolling back to previous version of the kernel fixes the issue. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
