 |
|
Hi all,
This is a phenomenon I cannot explain. Most probably I borked somewhere but I don't know what exactly I have done. So I hope that someone here could give me a hint.
Usb is managed by hotplug and it's doing a good job. Webcam and scanner are at my service whenever I want to use them.
I have a digicam too ( Canon Powershot Pro 90 IS ) which only root could use until recently. I've rectified the permission-issue by following the steps described in the gphoto2 documentation:
| Code: | | # /usr/lib/libgphoto2/print-usb-usermap >> /etc/hotplug/usb.usermap |
Then I copied the usbcam.group-file from /usr/share/doc/libgphoto2/linux-hotplug into /etc/hotplug/usb, renamed it usbcam and edited it so that group=camera has access to the digicam.
Then I made the file executable:
| Code: | | chmod +x /etc/hotplug/usb/usbcam |
I've switched on the camera and the permission-issue was no more:
| Code: | $ ls -lR /proc/bus/usb/
/proc/bus/usb/:
total 0
dr-xr-xr-x 1 root root 0 Aug 8 11:59 001
dr-xr-xr-x 1 root root 0 Aug 8 11:59 002
dr-xr-xr-x 1 root root 0 Aug 8 11:59 003

Gentoo still boots fine since then but when hotplug is being started I can watch it work with some scripts. I cannot see what it is - it is running too fast; something concerning drivers.
This happens for roughly half a minute. After finish the booting continues normally  and I can log in, startx etc... the system's still working reliably and stable - no harm done.
Does anyone have an idea?
TIA

Dear Gentooers,
Is it remotely possible that what I can see on boot is what I should see ? That the only mistake is that I think it is a mistake ?  
As a newbie I really should browse Duplicate Threads more than the other forums :
https://forums.gentoo.org/viewtopic.php?t=65642
Dracula describes the same happening on boot, only that s.th. isn't working right and dmesg doesn't tell what.

| Doesn't dmesg show the usb ports being probed? |

Dmesg is long and seems to probe all ports - it is too long for posting but I don't see any error messages.
gphoto2 --list-ports , gphoto2 --auto-detect , gphoto2 --summary give me the information that is to be expected when everything is right.

I have removed the script "usbcam" from /etc/hotplug/usb and hoped that this would normalize booting: no luck.
I tried to recognize what scripts are racing down the screen when hotplug starts and I could see snippets of "checkroot", "local" and "/etc/runlevel/boot" but I still don't have the slightest what is going on here.
Is it possible that the command chmod +x /etc/hotplug/usb/usbcam is wrong?
Isn't it better to cd into /etc/hotplug/usb and chmod +x usbcam?
There is a file "hotplug" in /etc/init.d. Could this be connected?
Since removing the pertinent file doesn't change the look and feel of the boot-process I'll leave the file where it is and keep looking and searching until I know what`s going on.
I'm still of the opinion that it is my fault.

While looking for answers to why hotplug initiates such a lava-stream of scripts on booting I've found fixes for the remaining issues and annoyances still left on my system.
I've even made the built-in mic of the Philips ToUcam usable. The audio quality is not too high yet it is working.
But I still haven't got the slightest what's going on with hotplug and whether this will lock me out of my system one of these nice days 
Any specialist of hotplug or rookie-mistakes out there
