mount USB Camera FC3
 

Hi,

I have nice little camera "Praktica DCZ 2.2 S" and I want to mout it on my newly installed fedora FC3.
It used to be possible with fedora FC1 and of course under Windows XP. On FC3 nothing much happens although the systems gives some signs that it knows about the camera. I have searched the web extensively without much success.

Here the symptoms:

1) when I connect the camera it acknowledges the connection by beeping.

2) dmesg shows me:
usb 4-2: new full speed USB device using uhci_hcd and address 4
(find /proc/bus/usb/004/004)

3) With "cat /proc/bus/usb/devices" I find a new entry:
T: Bus=04 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 4 Spd=12 MxCh= 0
D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=0d64 ProdID=0108 Rev= 1.00
S: Manufacturer=DSC
S: Product=DIGITAL CAMERA USB
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 0mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=00(>ifc ) Sub=00 Prot=00 Driver=(none)
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms

4) Then that is about it! No way to mount the camera
"fdisk -l" shows nothing

5) "gphoto2" cannot work of course and my camera is not in that gphoto2 data base anyway.

Any idea how to do this? For me that camera is just like a memory stick but those are selfdetected by FC3.

Many Thanks in advance!

Cheers, Frank

fdisk -l alone won't provide much in the way of anything useful - have you tried something along the lines ofas root, after plugging the camera in and selecting connect via usb (if appropriate) from the menu on the camera ?

Hi,

Thanks for your reply!! The command "fdisk -l /dev/sd*" does nothing independent if the camera is properly connected or not. Too bad it isn't that easy! It seems to me that there is simply a driver missing???

Happy about more suggestions!

Cheers, Frank

Well lets see a little more info from the following. Post all output info.
' fdisk -l ' I know it may only show /dev/hd* devices really looking for /dev/sd*
' cat /proc/scsi/scsi ' If detected should be foworded on to where fdisk can see.
' lsmod ' List loaded modules.

I would say some module is not loaded when device is plugged in. like usb_storage. If not there ' modprobe usb_storage '

kernel version?

May get down to the following. Get the SG3-Utils from here.
http://sg.torque.net/sg/index.html#U...nd%20sg3_utils
run the commands ' sg_map ' and ' sg_scan " and see what comes from that.

Also may require building a new kernel. Quite easy to do. Read over this post to see how to do if you wish to try. Some buggy issues with those precompiled kernels from up2date, syanptic, or yum.

While in there make sure you check multi-lun support. This might be the issue with the camera also. Not likely but possiable.

If you've had no problems using a usb thumbdrive, then you shouldn't need any more drivers for the camera (especially if it worked ok with FC1). Where are your usb devices normally held ? It may be under /dev/usb/* - if so, re-run the above fdisk command but with the new search path.

Hi,

Thanks! I will answer both last posts:

If I plug a memory stick I get automatically an entry in "/etc/fstab":

/dev/sdf1 /media/usbdisk vfat pamconsole,exec,noauto,iocharset=utf8,noatime,sync,fscontext=system_u:object_r:removable_t,managed
0 0

and of course "fdisk -l /dev/sd*" gives the expected result!

None of this is happening for my camera.

Sorry to say that I am no longer certain if it ever worked on FC1. Right
now I do not get it either on my FC1 machine.

Here more details:

fdisk -l (no memory stick but the camera)

Yes as a last resort I might recompile the kernel. I would hate to do that since
that would mean another stop whenever the kernel changes!

Cheers and Thanks again!

Frank

Sorry for the delay. Cold and flu yesterday. Odd to me if the thumbdrive works and the camera does not. I know what you mean when recompiling a kernel something else seems to not work.

Just out of curiosty, Looks like you have a multi card reader. Does that work for you?

At this time I have no other ideas other than compile a new kernel.

If you get it going please post your fix.

Hi,

Now it is me who is late, sorry! Well, I kind of gave up since the gphoto2 were quite negative in terms of providing any help. It seems that Linux will basically remain unsupported when it comes to drivers for not so popular devices. I am afraid about the future of Linux if that will remain like that! In conclusion any kind of periphery will probably NOT work under Linux! This means that I will remain doomed to stay dual-booted forever.

Anyway, besides this doomsday worries I did the obvious although it is like cheating: I took out the SD card out of my camera and plugged into the card reader and it worked - no surprise.

Sorry but that is all...
