Hello,
I have a Logitech Bluetooth dongle, used in HID mode, which gets unusable on
recent kernels (3.4-rcX: the 'removable' attribute was added) due to autosuspend
being enabled on its internal hub ports (the last of rule 42-usb-hid-pm.rules),
see also a thread on linux-usb here:
http://marc.info/?l=linux-usb&m\x133380762425041&w=2
Please exclude this receiver from autosuspend, as it makes it unusable.
Thanks,
Manuel Lauss
