Thanks for getting back to me,

4.11.11-300.fc26.x86_64 and 4.12.9-300.fc26.x86_64
 are showing identical settings - autosuspend definitely on for
device /sys/bus/usb/devices/2-1.3/2-1.3:1.0/0003:046D:C52B.0001/power

it shows in the powertop UI as good for both kernels and

Folder contents are autosuspend_delay_ms (can't open), control (auto),
runtime_active_time (0), runtime_status (unsupported),
runtime_suspended_time (0)

Alright, that means that both kernels are allowed to autosuspend the 
device, but apparently only 4.12 actually does so. Could you please 
confirm that with usbmon traces?

Thanks,
