Here's a dmesg snippet from another machine: Suspending device usbdev4.1 Suspending device usbdev4.1_ep81 Suspending device 4-0:1.0 Suspending device usbdev4.1_ep00 Suspending device usb4 hub 4-0:1.0: activate --> -108 suspend_device(): usb_suspend+0x0/0x30() returns -16 Could not suspend device usb4: error -16 PM: Image restored successfully.
