My HP Intel laptop drops all USB ports when I use the Bluetooth Internet connection for 30 minutes or so after a wake. I notice that the laptop also seems to be using power whilst suspended sometimes and Hibernate doesn't work. I'm running 18.04 Ubuntu Mate. rmmod and modprobe didn't revive anything on the usual modules but some self reference so cannot easily be removed.
Here is dmesg immediately after the bluetooth connection is lost: [39669.384218] ata2.00: configured for UDMA/133 [39669.466221] IPv6: ADDRCONF(NETDEV_UP): eno1: link is not ready [39669.490467] r8169 0000:03:00.0 eno1: link down [39669.490580] IPv6: ADDRCONF(NETDEV_UP): eno1: link is not ready [39669.491931] IPv6: ADDRCONF(NETDEV_UP): wlo1: link is not ready [39669.609788] IPv6: ADDRCONF(NETDEV_UP): wlo1: link is not ready [39669.677970] IPv6: ADDRCONF(NETDEV_UP): wlo1: link is not ready [39795.587223] xhci_hcd 0000:00:14.0: Root hub is not suspended [39798.567935] xhci_hcd 0000:00:14.0: xHC is not running.

After this, the laptop doesn't recognise any device plugged in to the USB ports - plugging and unplugging any device I've tried into any of the USB ports produces no response, not even dmesg entries. Strangely this also applies to bluetooth - it no longer works once USB has dropped (possibly the module is hung of the bus internally). Once this has happened only a reboot fixes it; I've not managed to find any combination of module unload/reload or suspend cycles to reinitialise things correctly.
