Nonretail consoles can use the ★ Debug Settings : Controller Setting to use USB instead of wireless.

Audio does not carry through USB in the case of a Dual Shock 4.

The reports arrive ~250 times per second (every ~4ms).

Value			Items	Remarks
0x05	0x01	-	Usage Page (Generic Desktop Controls)
0x09	0x05	-	Usage (Game Pad)	CA – A manual control or cursor device. A game pad minimally consists of a thumb-activated rocker switch that controls two axes (X and Y) and has four buttons. The rocker switch consists of four contact closures for up, down, right, and left.
0xA1	0x01	-	Collection (Application)	Start
0x85	0x01	-	Report ID (1)	Used by the FW to determine what data has been send or need to be transmitted
0x09	0x30	-	Usage (X)	DV – A linear translation in the X direction. Report values should increase as the control’s position is moved from left to right. (for sticks)
0x09	0x31	-	Usage (Y)	DV – (Y direction- values should increase from far to near)
0x09	0x32	-	Usage (Z)	DV – (Z direction- values should increase from high to low)

A typical example is four switches that are capable of generating information about four possible directions in which the knob can be tilted. Intermediate positions can also be decoded if the hardware allows two switches to be reported simultaneously. (for D-pad)

T-PAD: auto incrementing number to track last update?

[35]

T-PAD: tracking numbers, unique to each finger (№1) down, so for each lift and repress, it gets a newly incremented figure.

[36 - 38]

T-PAD: each finger (№1) location/positional data: static upon finger lifting, to maintain state.

To decode, each coordinated (x & y) is using 12 bits, you need to mask/split and swap the middle byte : e.g: 0x8a 4|0 28 → 0x08a 284 → x= 138 y= 644 ^[2]

Notes

↑ if NULL:
↑ T-PAD resolution (retail): 1920x943 → x=0-1919 and y=0-942 (2¹² = 4096 when 2bits¹¹ = 2048 would have been enough to fit into the resolution)
↑ if NULL:

see Button mapping

Speculation: sound, rumble (active: 1-255 / Left-Right small or large?) and LED (Color changing 8 bits for each of the R, G, and B primaries : 13-255?) are only carry through (always enable) blue-tooth.

report ID 0xA3 seems to be some sort of time-of-manufacture identifier, it contains a date and time as a string in the beginning, ".Aug 3 2013.....07:01:12...........1....I....."

AC 9E 17 94 05 B0 is PS4 (Host) Bluetooth MAC Address (in proper MAC format, it is B0:05:94:17:9E:AC), AC 9E 17 is the LAP and 0x94 is the UAP, 05 B0 is the NAP, this was verified using a Bluetooth sniffer.

The 16 bytes that follow immediately after the BD_ADDR is the link key that is used to authenticate the DualShock 4. When a Bluetooth connection is established, this link key is used for authentication.

I am guessing that 8B 09 07 6D 66 1C means something, it's different on a different controller, it seems to be the Bluetooth MAC Address of the DualShock 4. in proper MAC format it is 1C:66:6D:07:09:8B in this example.
