-Subject: HID: Revert "Revert "HID: Fix logitech-dj: missing Unifying device issue""
-
-This reverts commit 8af6c08830b1ae114d1a8b548b1f8b056e068887.
-
-This patch re-adds the workaround introduced by 596264082f10dd4
-which was reverted by 8af6c08830b1ae114.
-
-The original patch 596264 was needed to overcome a situation where
-the hid-core would drop incoming reports while probe() was being
-executed.
-
-This issue was solved by c849a6143bec520af which added
-hid_device_io_start() and hid_device_io_stop() that enable a specific
-hid driver to opt-in for input reports while its probe() is being
-executed.
-
-Commit a9dd22b730857347 modified hid-logitech-dj so as to use the
-functionality added to hid-core. Having done that, workaround 596264
-was no longer necessary and was reverted by 8af6c08.
-
-We now encounter a different problem that ends up 'again' thwarting
-the Unifying receiver enumeration. The problem is time and usb controller
-dependent. Ocasionally the reports sent to the usb receiver to start
-the paired devices enumeration fail with -EPIPE and the receiver never
-gets to enumerate the paired devices.
-
-With dcd9006b1b053c7b1c the problem was "hidden" as the call to the usb
-driver became asynchronous and none was catching the error from the
-failing URB.
-
-As the root cause for this failing SET_REPORT is not understood yet,
--possibly a race on the usb controller drivers or a problem with the
-Unifying receiver- reintroducing this workaround solves the problem.
-
-Overall what this workaround does is: If an input report from an
-unknown device is received, then a (re)enumeration is performed.
