We only care about whether our direct parent is removable, not whether any further points up the tree are - the kernel will take care of policy for those itself. This enables autosuspend on devices where the root hub reports that its removable state is unknown.

# Enable autosuspend for qemu emulated usb hid devices
|
|
|
|
# Note that there are buggy qemu versions (0.13 & older) which
|
|
# advertise remote wakeup support but don't actually implement
|
|
# it correctly. This is the reason why we need a match for the
|
|
# serial number here. Old, broken versions have serial "1".
|
|
# It has been changed to "42" after fixing the bug to indicate
|
|
# remote wakeup is working.
