 Posted: Tue Apr 20, 2004 11:39 pm Post subject: Problem mounting a digital camera |
 |
|
I'm trying to connect my Sony Cybershot DSC-P8 camera to my ThinkPad 390E laptop via the USB port.
In many places I've read that I need to execute the following command:
| Code: |
mount -t vfat /dev/sda1 /mnt/camera
|
But when I try this the system tells me that the device does not exist.
| Code: |
cockatoo root # mount -t vfat /dev/sda1 /mnt/camera
mount: special device /dev/sda1 does not exist
|
Can someone please explain the what the /dev/sda1 device is and how I can create it? |

Please search the forum! (Please realize that just that mount command isn't enought) 
A hint: /dev/sda is a virtual scsi disc representing your camera's memory. It's automatically created (-> devfs) when you connect your camera via usb. You need scsi general and scsi disc support for that (besides, USB mass storage support as well).
That should be info enough, I'm sure you'll be able to find the solution here. Hopefully your cam does support the usb mass storage standard..
Good luck,
Sebastian |

Thanks for your reply Sebastian. I have searched the forums but I'm obviously still trying to understand what's important in order to get this working. I'm a newbie when it comes to USB and Gentoo.
I have actually tried to follow this HOWTO: https://forums.gentoo.org/viewtopic.php?t=53537 and found some other threads which have improved my understanding. However I'm still a frustrated user who has been enjoying using and learning about Gentoo but has pictures to download from his new camera and no way (yet) of doing it! 
Whilst following the above HOWTO instructions the first point at which something doesn't work is the modprobe for usb-uhci. This is what I get.
| Code: |
cockatoo root # modprobe usb-uhci
/lib/modules/2.4.20-gentoo-r6/kernel/drivers/usb/usb-uhci.o: 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
/lib/modules/2.4.20-gentoo-r6/kernel/drivers/usb/usb-uhci.o: insmod /lib/modules/2.4.20-gentoo-r6/kernel/drivers/usb/usb-uhci.o failed
/lib/modules/2.4.20-gentoo-r6/kernel/drivers/usb/usb-uhci.o: insmod usb-uhci failed
|
And this is what I get from running lsusb -v:
| Code: |
cockatoo linux # lsusb -v

And when I run dmesg the relevant snippets are:
| Code: |

usb.c: registered new driver hub

and
| Code: |

I've tried recompling the kernel after adjusting the USB options. Here are the relevant options in my config:
| Code: |

I would love to understand this stuff better and, what's more, download my pictures! And I would prefer not to have to resort to Windows XP.
Any ideas as to what I should be checking or trying next?  |

How are you re-compiling your kernel? Are you certain you have correctly put your new recompiled kernel into the right place? Are you certain that you have booted into your newly recompiled kernel?
It looks to me like when you run "modprobe usb-uhci" it is rejecting the module because it was compiled as part of a different kernel than the one that is currently running.
So, if you arent already, I would recomend using "genkernel --config" to compile your kernels as this automatically takes care of putting the kernel onto your boot partition (it does all the steps of a kernel recompilation for you!)
Also, you can see what kernels are currently on your boot partition by running:
| Code: |
mount /dev/hda1 /boot
ls -l /boot
|
Check the timestamps on the kernel* files and make sure the one that is the newest is the one you are booting into (as configured in /boot/grub/grub.conf).
There could be a lot of reasons things are not working for you, but hopefully this info helps you get on the right path to getting them to work... then tutorial you are using is pretty thorough, so you should be able to follow it and have your camera mount.
Also, after you get your camera to mount, be sure to check out the "gphoto2" ebuild, lots of cool things are possible with it!

Have you tried /dev/sdb1 instead of /dev/sda1?
My camera shows up as either depending on which usb port i plug it into.
