Reassigning to powertop package for a first look - I upgraded a PC
laptop to 17.10, and I am seeing two usb devices (camera and keyboard)

they were not before the upgrade).

Reproes with the v4.14 kernel.
Power usage on idle is
4.14:~8W
4.13:~10W
4.10:~7W
There appears to have been a significant regression in power use from
4.10 to 4.13 that has been partially addressed in 4.14.
I got curious, and I get the same 100% busy report if I boot with the
legacy 4.10.37
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.14 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix
Thanks for the bug report, but the driver is a kernel component so I am
reassigning it.
Only if you saw the 'bluetoothd' process spinning would this be assigned
to BlueZ.
** Package changed: bluez (Ubuntu) => linux (Ubuntu)
