Hey,
Logitech usb bluetooth dongles that have a HID mode need to be retriggered
into HCI mode after S3 just like Dell ones otherwise they'll just disappear
and my bluetooth stops working :/
See attached patch for a potential fix.

Subject: [PATCH] hid2hci: re-trigger switching for logitech devices after S3
When going to S3 logitech usb dongles will loose their bluetooth interface, so
the switch needs to be retriggered afterwards in the same way that's needed for
Dell devices.
