Hello, my USB-2 mouse and keyboard works when connected while I'm booting. If I replug them, I get in the dmesg the following lines and they no longer work: [ 48.739931] xhci_hcd 0000:0c:00.0: Error while assigning device slot ID: Command Aborted [ 48.739938] xhci_hcd 0000:0c:00.0: Max number of devices this xHCI host supports is 64. [ 48.739941] usb usb1-port1: couldn't allocate usb_device [ 48.776022] xhci_hcd 0000:0c:00.0: WARN: xHC save state timeout [ 48.776032] xhci_hcd 0000:0c:00.0: PM: suspend_common(): xhci_pci_suspend+0x0/0x150 [xhci_pci] returns -110 [ 48.776041] xhci_hcd 0000:0c:00.0: can't suspend (hcd_pci_runtime_suspend [usbcore] returned -110) If I plug them in USB-3 port they work. Is this a known issue? Is there a workaround? Has someone a patch that I can test? Find the output of dmesg, lsusb, lspci, dmidecode and lscpu here: https://tg.st/u/6c2aa1c7120cc64e2d90863dc3afea4d4c9e3d6f56666fc681c02ee5f0728130.txt I'm running v6.2.1 with a Debian bookwork userland and have the latest linux-firmware from git installed.
