[Pi5] Slow initialisation of USB

[procount]

Model: Pi2, Pi Zero 2
PINN: v3.8.9

USB keyboard and mouse take too long to be detected, making pressing the Shift key ineffective at boot up to enter the recovery menu.
A workaround is to set forcetrigger in cmdline.txt

Says "Pi5" in the subject line, but "Pi2" in the text? 🤔

[procount]

Maybe my nomenclature is a bit ambiguous. By [Pi5] I mean "PINN v3.8.9 beta suitable for the Pi5", which is actually also applicable to all models.

[procount]

@lurch any idea why usb init could be so slow?

[lurch]

Not off the top of my head. And I'm still away from home on my festive break, so I currently don't have any Pis for testing with either.
Have you got any necessary USB / keyboard drivers compiled directly into the kernel, and not as loadable modules?

[procount]

No modules. All built in like before. Should be the same drivers. Maybe specific to that kernel (7?) Or in combination with 6.1 version 🤷‍♂️
Needs more analysis...
