Sorry it took so long to get back to this.

The patched kernel results in the output for the RPi keyboard:

ugen2.2: <vendor 0x05e3 USB2.0 Hub> at usbus2
uhub6 on uhub1
uhub6: <vendor 0x05e3 USB2.0 Hub, class 9/0, rev 2.00/32.98, addr 1> on usbus2
uhub6: MTT enabled
uhub6: 4 ports with 4 removable, self powered
ugen2.3: <vendor 0x04d9 RPI Wired Keyboard 4> at usbus2
ukbd2 on uhub6
ukbd2: <vendor 0x04d9 RPI Wired Keyboard 4, class 0/0, rev 2.00/1.40, addr 2>
on usbus2
kbd4 at ukbd2
uhid1 on uhub6
uhid1: <vendor 0x04d9 RPI Wired Keyboard 4, class 0/0, rev 2.00/1.40, addr 2>
on usbus2

Looks good to me.

On a RPi4B the patched kernel continued to work.
