3.16.48-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Bristot de Oliveira <bristot@xxxxxxxxxx>
commit c14022bfd2eb2d2ece74a405dfbdb02a829c07bc upstream.
The device which identifies itself as a "USB Keykoard" (no typo)
with VID:PID 1a2c:0027 does not seem to be handling the reports
initialization very well.
This results in a "usb_submit_urb(ctrl) failed: -1" message from the
kernel when connected, and a delay before its initialization. It can
also cause the hang the system.
This patch adds the quirk for this device, which causes the delay
to disappear. It is named as "USB Keykoard2" because the "USB Keykoard"
already exists.
