Public bug reported:
On my laptop the kernel will sometimes drop the USB hub. 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.
Relevant snippet of dmesg:
