5.9.1 broke my Apple FaceTime HD Camera webcam. It turns on but it doesn't seem to output anything. Any idea on how to fix it other than downgrading? (obviously) maybe it's a bug upstream? IDK.

Somebody took a picture of me.
And then the camera broke.
If you just updated the kernel without restarting (the module wasn't already loaded from the previous kernel), then you'll have to restart and try it again.
I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...
Look ma, no mouse.

If you just updated the kernel without restarting
still doesn't work I wouldn't start a thread without restarting first.

Nothing in dmesg?

Now checking also if usb hub and network card work as they should. I will also check on linux58 if there are any evident differences
UPDATE
network card works
USB doesn't works but maybe slower than usual? IDK
also.....is it listed as USB3? it is not. maybe we getting somewhere. I will add below dmesg from linux58 as soon as I downgrade and reboot

Is to add irqpoll as boot parameter but it may significantly impact system performance. I will file a bug report upstream.

Check your irqs with /proc/interrupts
Usually a device connected via usb is on a irq or irq sharing port.

The very right shows which kernel module is on which irq.
Since the camera is a usb device, it'll most likely show up as just being under a usb irq.
To find out which usb hub the camera is on, you'd simply do lsusb and if you want to match any possible modules (which don't appear to be there), lsusb -vv.
I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...
Look ma, no mouse.

can't get debug descriptor: Resource temporarily unavailable

It's plugged into bus 3 which would be irq 38...that's not the irq 18 that it's complaining about disabling.
It looks like it is just using the usb uvc driver (no nothing special).
Probably won't be any different between kernels.
Unless there was a problem with the usb driver (host or uvc).
Could possibly put debug options on the kernel modules, but may not tell anything either.
lsmod would show what modules are tied together with their dependencies.
Not sure if any of the v4l2 utilites would give any useful information.

It looks like irq 18 is your firewire port.

Yeah I know, I don't see many solutions: downgrade (thank you, but no, thank you) or use irqpoll and wait and test new versions as they come along and this is what I am planning to do. 5.9 works weird with all kind of hardware but it will be much better in a couple of months.
