Bug Description

Impossible to connect digital camera acting as USB mass storage to Ubuntu 5.10

I have HP PhotoSmart M307 digital camera which is configured to connect to computer as USB disk drive. This works perfectly with SuSE 9.3 and FC3.

After I installed Ubuntu 5.10 over FC3 on the same machine, I haven't been able to connect the camera to the computer anymore. It still works with my other computer running SuSE 9.3. I'm not able to mount the USB drive automaticly nor manually through mount command. When camera is connected, "sudo fdisk -l" hangs.

I'm not sure this is bug of hal, but since I'm not able to mount the USB storage even manually, it shouldn't be problem of gvm. I noticed that there are similar bug reports, but in those cases manual mount has worked or installing libpmount0.0 or some other package has fixed the problem. I've tried those fixes and work arounds with no luck.

I tested the camera (HP M307) with Dapper live CD with same results. The USB HD does not mount automaticly nor it isn't possible to mount it manually. "fdisk -l" hangs.

Same behaviour on two different laptops.

This explains it; the kernel seems to be unable to detect the partition table on the camera. So /dev/sda exists, but no partition devices.

When connecting the same camera to SuSE 9.3 kernel doesn't detect the partition table either(?). Ouput of dmesg on SuSE:

It still does mount properly both automated and manually by giving command "mount /dev/sda /mnt/".

I also tested Ubuntu 5.10 with self compiled vanilla kernel 2.6.15 with no better luck. I used Ubuntu's config though and made only oldconfig ("make oldconfig)" before compiling.

Aah, I got confused, sorry. It seems that the camera does not have a partition table in the first place, but just has a file system on the raw device /dev/sda. Then it is indeed a hal problem.

So, hal incorrectly detects 'block.is_volume = false (bool)', which should be true for you. Can you please generate a full hal debug output, as described on the second half of http://wiki.ubuntu.com/DebuggingRemovableDevices ? This could help me to find out the problem.

Thank you!

@Juergen: /proc/bus/usb is deprecated in Dapper; this is now under udev's control in /dev/bus/usb.

the only way i can get my usb storage devices to work is by running this once during each session:

sudo modprobe -r ehci_hcd

Ah, that sounds familiar. Failures of the USB 2.0 driver are unfortunately very common (see bugs 15563, 16541, 17168, 41229, 27889). I'm closing this one as duplicate.
