Without this quirk the device keeps disconnecting from the bus (and is re-enumerated) unless opened (and kept open, should an input event occur). Note that while the device can be run-time suspended, the autosuspend timeout must be high enough to allow the device to be polled at least once before being suspended.

HID: input: Fix TransducerSerialNumber implementation 2014-11-14T18:10:26+00:00 Jason Gerecke killertofu@gmail.com 2014-09-23T18:09:28+00:00 fedb1e978b3d017064e9591c185049538a5164ea commit 5989a55a4c9aafba8b152c6bf52244510c2b88b9 upstream. The commit which introduced TransducerSerialNumber (368c966) is missing two crucial implementation details. Firstly, the commit does not set the type/code/bit/max fields as expected later down the code which can cause the driver to crash when a tablet with this usage is connected. Secondly, the call to 'set_bit' causes MSC_PULSELED to be sent instead of the expected MSC_SERIAL. This commit addreses both issues.

In the Dell XPS 13 9333, it appears that sometimes the bus get confused and corrupts the incoming data. It fills the input report with the sentinel value "ff". Synaptics told us that such behavior does not comes from the touchpad itself, so we filter out such reports here. Unfortunately, we can not simply discard the incoming data because they may contain useful information. Most of the time, the misbehavior is quite near the end of the report, so we can still use the valid part of it.
