Greetings,

I am currently slaving away trying to get my digital camera working in mandrake 9.1. My camera uses usb mass storage and all three modules are present in lsmod:

However I have had absolutely no luck in actually mounting my camera. A few times the mount command succeeded but all I got were a load of link files from sda. (?)

When trying "mount -t devfs /dev/sda1 /home/roy-svork/Camera", initalially it said special device sda1 not found, but just now it has been succesfull but is just a mirror of /dev

i have tried with vfat, devfs, usbfs all to no avail.

The only clue is some messages which I think should not occur in /var/log/messages:

so any ideas? AHMA

What camera is this?

With the camera plugged in what does the following commands show.

cat /proc/scsi/scsi

cat /proc/bus/usb/devices

cat /proc/bus/usb/drivers

/etc/modules

I assume the storage media is vfat. you can use this command. Make sure you have created the directory like I am using in the example below.

mount -t vfat /dev/sda1 /mnt/camera

Does your camera use USB 2.0 or USB 1.1? If it uses USB 1.1, then your problem may be because it is using the USB 2.0 module (usb-uhci), whereas USB 1.1 uses the 'usb-ohci' module. 'usb-ohci' is missing from your lsmod ouput. Try:

modprobe usb-ohci

and then try your camera again, using the mount command given above by Brian1.

I get the following:

[root@localhost roy-svork]# modprobe usb-ohci
/lib/modules/2.4.21-0.13mdk/kernel/drivers/usb/usb-ohci.o.gz: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
modprobe: insmod /lib/modules/2.4.21-0.13mdk/kernel/drivers/usb/usb-ohci.o.gz failed
modprobe: insmod usb-ohci failed

which does not seem to improve things...

and in response to earlier post:

I think things may have become a little confused. The box I am currently sitting at uses USB 1.1 and uses the UHCI module. An old PII box of mine (now deceased) used the OHCI module for USB 1.1. I've just read a little bit in the kernel source Docs directory, and it seems that USB 2.0 uses the EHCI module. I think the uhci/ohci thing is simply a matter of two early competing standards. UHCI = Universal Host Controller Interface; OHCI = Open Host Controller Interface. EHCI = Enhanced Host Controller Interface, perhaps?

Thymox, thanks for setting me straight; I've been operating under the misconception that OHCI = USB 1.1 and UHCI = USB 2.0 (U = Ultra - wrong, of course). My system has both object modules, with only OHCI being mentioned by lsmod. I presumed that UHCI was not loaded because I had no USB 2.0 devices. However, after reading your post, I found ehci-hcd.o in a sub-directory 'hcd' of where the usb kernel modules are stored.

Roy-Svork, sorry for the confusion. This is how I got my digital camera to work in Mandrake 9.1; it might help:

http://www.linuxquestions.org/questi...threadid=74030

You never did identify this hardware, what is the manufacturer and model of this camera?
Is this a 'vanilla' (out of the box) Mandrake kernel, or did you compile it yourself?

This guy never got a response:

The device 0733 is not listed at http://www.qbik.ch/usb/devices/searc...p?pattern=0733 but that list is not all inclusive.

Your system looks like it's getting the right modules for a SD card,
via your listing (sd_mod):
-usb-storage 72952 0
>scsi_mod 103284 5 [scsimon sd_mod sr_mod ide-scsi usb-storage]
-usb-uhci 24652 0 (unused)
-usbcore 72992 2 [usb-storage usb-uhci]

Anyone know where Roy-Svork might get a driver for this one???
Or anyone have a success story with it?

A common factor with this problem seems to be usb-uhci. Certainly the first link given by faheyd lists usb-uhci as the usb module. My camera (and a usb printer and scanner) work perfectly well with usb-ohci. Perhaps the next thing to try should be:

rmmod usb-uhci
modprobe usb-ohci

and see how it goes.

This is a shot in the dark since I use straight scsi hardware, but maybe the cdrom is using /dev/sda1. Try this, use /dev/sdb1

Leave out the -t vfat. you can use this command. Make sure you have created the directory like I am using in the example below.

mount /dev/sdb1 /mnt/camera
