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.
