> This adds a special case in the HIDP core for the Dualshock 4 controller. > The controller only recognizes output reports with the report type 0x52 and only accepts reports sent via the ctrl channel. Which part of the system is 'at fault' here, is it simply the DS4 behaving incorrectly or that Bluez is not picking up some data or that 'we' are just the incorrect method to send the data (in the hid-sony kernel driver)? I noticed that the BT HID spec notes a 'HID control' channel in the example descriptor in table 5.3.3 as 'Parameter 0'. The DS4 gives this in it's SDP report -- Attribute 0x0004 - ProtocolDescriptorList Sequence Sequence UUID16 0x0100 - L2CAP UINT16 0x0011 <---------- 'HDI Control' PSM 17 Sequence UUID16 0x0011 - HIDP -- Shouldn't Bluez be remembering this and sending accesses to this PSM in the appropriate mode? Just looking to fix the problem where it really exists, without just working around specifically for the DS4. Simon
