Subject: xhci_hcd: USB-2 devices are not usable after replug
Date: Mon, 27 Feb 2023 19:57:29 +0100 [thread overview]
Message-ID: <Y/z9GdHjPyF2rNG3@glanzmann.de> (raw)
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:

I'm running v6.2.1 with a Debian bookwork userland and have the latest
linux-firmware from git installed.
Cheers,
Thomas
