ACRUX gamepads not happy with autosuspend?

ACRUX gamepads not happy with autosuspend?

[Dmitry Torokhov]

Jiri, Oliver,

It looks like ACRUX game controllers do not like autopm. There is
a bug report over at Ubuntu's launchpad:

	https://bugs.launchpad.net/ubuntu/+source/joystick/+bug/448446

that states that once device is plugged in the light ion it turns on
briefly and then goes off and from that point on nothing comes from
the device. They deal with it by having an application open the jsX
device as soon as it appears and that makes gamepad work - but it
is obviously not a solution.

It looks like we either need to disable autosuspend for these devices
or maybe kick the device harder when userspace tries to open it so
that it wakes up if it went to sleep.

(Sergei, have you tried disabling autosuspend on your box if it is
enabled?)

Also, if one attempts to boot the box with gamepad already connected
then the driver gets confused and will attempt to reset the device
indefinitely:

[   32.430271] drivers/hid/usbhid/hid-core.c: can't reset device, 0000:00:1a.2-1/input0, status -32
[   32.446271] drivers/hid/usbhid/hid-core.c: can't reset device, 0000:00:1a.2-1/input0, status -32
[   32.462271] drivers/hid/usbhid/hid-core.c: can't reset device, 0000:00:1a.2-1/input0, status -32
[   32.478272] drivers/hid/usbhid/hid-core.c: can't reset device, 0000:00:1a.2-1/input0, status -32

Under Windows the device works well with the standard driver; no
vendor specific drivers is required... Any ideas?

Thanks!

That report shows that the symptoms are consistent with autosuspend,
but it doesn't show that autosuspend was on.

If autosuspend is enabled simply opening the device file will keep the
device active as it does not suport remote wakeup.

Something like
sleep 5000 </dev/input/js0
should fix the issue.

You can try the attached patch. I doubt it works.

That would be my first question -- who enabled autosuspend, if it was 
really on? I thought it should be still off by default, shouldn't it?

It is off by default, but that doesn't stop Ubuntu having a udev rule to
switch it on or patching the kernel, so it might be on. We simply need
to know.

Does it mean that autosuspend is enabled?

No, this means that if it is enabled a heuristic timeout of 2s is used.
That is if your device has been being idle for 2s, it will be autosuspend.

Whether it is autosuspended at all all is controlled in the "level" attribute.

on = no autosuspend
auto = autosuspend activated

Hmm, Sergei says that fiddling with autosuspend values (nor disabling it
altogether by recompiling without CONFIG_USB_SUSPEND) helps. If device
left unopened then attempts to open it (and thus start traffic) at a
later time fail.

Sergei, what happens if you have the device plugged and compile HID as a
module and then unload/reload the driver and try opening the device
right away? Does it work or is it still dead?

Thanks.

I found old bug dedicated to this problem:
http://kerneltrap.org/mailarchive/linux-usb-devel/2007/11/2/378569

In additional there is similar bugs in other distributions with
different kernel versions:
