Subject: [PATCH] HID: get rid of HID_QUIRK_NO_INIT_REPORTS
It looks like a bunch of devices do not like to be polled
for their reports at init time. When you look into the details,
it seems that on those that are requiring the quirk
HID_QUIRK_NO_INIT_REPORTS, the driveris fail to retrieve part
of the features/inputs while others (more generic) work.
IMO, it should be acceptable to remove the need for the quirk
by applying it by default. On the small amount of cases where
we actually need to read the current values, the drivers
in charge (hid-mt and wacom) already retrieve the features
manually.
There are 2 cases where we might need to retrieve the reports at
init:
1. hiddev devices with specific use-space tool
2. a device that would require the driver to fetch a specific
feature/input at plug
For case 2, I have seen this a few time on hid-multitouch but it
is solved in hid-multitouch directly by fetching the feature.
I hope it won't be too common and this can be solved on a per-case
basis (crossing fingers).
For case 1, the hiddev documentation provides an ioctl to do the
init manually. A solution could be to retrieve the requested report
when EVIOCGUSAGE is called, in the same way hidraw does. I would be
tempted to not change the behavior and hope that we won't break any
userspace tool.
Note that I don't think hidraw would be affected and I checked that
the FF drivers that need to interact with the report fields are all
using output reports, which are not initialized by
usbhid_init_reports().

Hi,
Sending this partly as an RFC, partly as an actual patch :)
I think it would be good to have such a removal, but I am not so sure
about the implications. I think Windows does not retrieve the features/input
by default, so I think this would help us for future devices.
I don't know what to do about hiddev too. I don't know if we have actual
users besides some debugging tools. And hidraw is much better than hiddev,
so ideally, I'd like to remove it some way.
Anyway, what do you think about it?
Cheers,
Benjamin
