Created attachment 282123 [details] dmesg output On my ThinkPad E585, with a Ryzen 5 2500U, my XHCI driver crashes when a USB device is plugged into any port. Steps to Reproduce: 1. Boot the system normally. 2. Plug in a device to any USB port. Actual Results: The USB device fails to register; the XHCI driver crashes and is unusable. Device does not show up in the output of `lsusb`. Tail of dmesg output (full output attached): [ 51.276650] xhci_hcd 0000:05:00.4: Refused to change power state, currently in D3 [ 51.276658] xhci_hcd 0000:05:00.3: Refused to change power state, currently in D3 [ 51.277051] xhci_hcd 0000:05:00.3: enabling device (0000 -> 0002) [ 51.277074] xhci_hcd 0000:05:00.3: WARN: xHC restore state timeout [ 51.277077] xhci_hcd 0000:05:00.3: PCI post-resume error -110!

I've done more investigation: - I disabled laptop_mode which was running by default (I assume that was messing with idle power state), and USB works until the laptop is suspended, with a slightly different message upon resume: [ 127.865337] xhci_hcd 0000:05:00.3: Refused to change power state, currently in D3 [ 127.877353] xhci_hcd 0000:05:00.3: enabling device (0000 -> 0002) After plugging in a USB device, it outputs: [ 135.368383] xhci_hcd 0000:05:00.3: Error while assigning device slot ID [ 135.368393] xhci_hcd 0000:05:00.3: Max number of devices this xHCI host supports is 64.
