[linux-uvc-devel] Quanta Computer Inc. Astro HD Cam, not initializing at boot

[Massimo B. <mas...@gm...>]

Hello everybody,

I previously posted to lin...@li... which seems to be dead.

This chinese camera does not initialize correctly at boot:

Bus 003 Device 004: ID 0408:2090 Quanta Computer, Inc. Astro HD Camera

After replugging it works fine.

I'd like to forward you a copy of my report on Gentoo:

When booting with this device plugged, it is not usable and blocking other audio
devices:

$ pacmd list-sources
Daemon not responding.

The syslog has continuously repeating this line:

[kernel] usb 3-7: 4:1: cannot set freq 44100 to ep 0x84
[kernel] usb 3-7: 4:1: cannot set freq 44100 to ep 0x84

rmmod and modprob'ing uvcvideo again shows:

Unplugging the usb cam, restarting pulseaudio and replugging the cam again makes
it work:

# uname -r
5.6.12-gentoo

Same on 5.7.4-gentoo.

What can I do to solve it at boot without re-plugging the hardware?

Just trying to rmmod and modrobe again does not solve the issue if not re-
plugging the hardware:
