Can't find my USB-Camera anymore.

English Hardware
1

After installing openSUSE 11.2 everything worked well (instead of wlan working not continuously, but that’s not the topic).
Now my computer stopped registering the camera (it’s a Canon Power Shot A540).

I already tried to add it with gphoto in digiKam - the automatic search did not find it - after a manual registration gphoto could not connect to it (although it was plugged and switched on).

The order lshal dumped 103 devices from the global Device List
The order lshal -m started monitoring device list, but comes to no end

fdisk -l shows me my hard drive with all particions plus a mobile hard drive (connected via USB) but no camera (it’s still plugged and turned on)

after many hours and reading of many forum threads I don’t know any further - can anybody help me find the solution for my prob?

Great thanks

what does lsusb show from a su terminal

Bus 001 Device 001: ID Id6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 045e;0040 Microsoft Corp. Wheel Mouse Optical
Bus 002 Device 001: ID Id6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 058f:9254 Alcor Micro Corp. Hub

That was with the camera connected?

And this: Alcor Micro Corp. Hub
Is what?

Yes, the camera was connected and switched on.

I had removed an external hard drive (running via USB) and an external USB-hub to connect the camera directly.

I have no idea, what the Alcor Micro Corp. Hub is.
I have an internal USB-hub via PCI on the mainboard, but that doesn’t work at all (drives connected there are never registered by the computer).

At the normal USB-ports are only the mouse and the camera connected.
When I connect something different at the second port, it works.

So you are saying some of the Mobo USB ports do not function?

Have you looked for a BIOS update.

Sorry, I have to take back my words about the non-working USB-ports. I’ve just tested them and they work well - they are at Bus 002 and recognize everything (USB-hard drive, mp3-player) but my camera.

I have tested the hard drive and the mp3-player connected to Bus 001 and Bus 002 and they showed up everytime.

I always thought BIOS was ROM - so I never thought I could make an update.
Where can I find an update for a ASUS-Mainboard?

asus have a web site and updates for many of their boards are easy, I have one.
You have to download the .bin file - something like 1020.bin, that’s just an example, there is a flashBIOS utility in the BIOS itself which you point to the hard drive where you saved the update (I think it needs to be a FAT or NTFS partition) but now you say your usb ports are ok, I’m not sure it’s necessary. BIOS updates are best avoided if possible.

As I read that a BIOS-update can harm a computer I’m glad I can leave it.
But I still can’t get connection to my camera.

10

You have tried it in all the usb port locations?

Try booting the 11.2 live cd, see if it responds

I’m sorry to take your time, but I can’t find the 11.2 live CD (despite my search).
All I found was the KDE live CD (which I already have) but with it my problem was still the same - mp3-player found at three of four ports (one port of three at Bus 002 didn’t work), camera nowhere found.

Bad decision. BIOS updates often solve problems with hard drives’ controllers, USB and PCI devices.

In most cases, you can roll back.
