Hello all of my friends,
After trying Redhat 8, Fedora core and then Yoper, it seems (just a guess) I want to stick with slackware. I just want a distribution which is clean, so fast, standard, bug-free and of course, source based; for installing all the packages easily. So far, slack has owned fairly all of these charachteristics. But, look at this point please: There are problems that are related to Linux generally and not to a specified distribution. Some of them do have solutions and some don't. I have never encountered such problems (either solvable or without solution) in a REAL COMMERCIAL product. After paying TONS of dollars for MatLab and its toolboxes, I just layed while installation and right away after installation I started to write my codes. I can't imagine Octave will do as good as MatLab at all. I am satisfied with the product completely because it is even better than Windows version. Another example is CATIA. Most of corporations use linux version of CATIA rather Windows version. Yes, commercial products.
But it's ok. I love linux. I am a fan of open sourse and I have only linux on my box. I am not an expert also not a newbie. I don't like GUI's and I love terminal! It's ok if the way for reaching your purpose in linux is long. It's ok if the way is hard to understand and non suitable for newbies. It's ok if you have to spend some time to reach the end. It's ok if the way is not like a breeze. But, there is a standard way for reaching any aim. Everyone expects that if he went into the way, then he would found his end. But what happens if you can't reach your aim through the standard way?
All of us must admit that there are lot's of problems in linux that even the standard way does not approach anything. Just wasting valuable time ...The so valuable time which never backs again. We must admit that all the people are not computer science engineers. Everyone wants his own works to be done.
I don't know till when this tragedies will continue. In world of communication, still most of modems are not supported! In 2005 A. D. most of drivers still are built for kernel 2.2.x!!!!! It's funny!
After a tragedy about mounting cd-roms as non-root users, after a tragedy about building acceleration for non-nvidia cards, after another tragedy about ....
Now, another tragedy is flowing: Slackware can't recognize my Concord eye-Q duo 1300 digital camera and mount it as mass-storage usb device. I have put 4 days (day and night) thouroughly on this topic. Viewing any page related to this, it just wasted my time. All were the standard ways which never work! All were the funny scripts do just this command and nothing more:
mount /dev/sda1 /mnt/"a place in the hell" !!!!!!!!!!!!!!!!!!!!!
I don't want to explain more. The problem is quite obvious: It can't attach the device as a scsi device; so nothing goes right.
The bare.i (default) kernel has all the needed modules and drivers(with built in scsi support & scsi disk support and usb-uhci and usb-storage and other needed stuff as modules).
It uses hotplug; although manually setting the parameters and modules has no effect.

I am using slackware 10.1.
Any help, any comment, any tip, any new hint is really really appreciated. Thanks in advance and sorry for the bad literature! I am quite angry!
Great Cheers,

As far as I can see the scsi modules are not loaded:

- scsi_mod
- sd_mod

You need these 2 modules loaded if you want connect a usb-storage device.
They are simulated scsi disks.

Try manually loading these modules with modprobe (as root)

Hopes this help you a little bit

Hey...


use:


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


remember that the cam will need to be mounted as fat file system , and that 'camera' is the suggested 'place' where you should mount it.



And by the way... all you said is correct, BUT do not forget that today things are really easier, and are changing and becoming better every day.

bye

My canon digital elf s500 works perfectly under linux. And the linux apps are alot more comprehensive too. I like digikam and find it alot better then any windows app I've seen.

First, thanks alot for your reply. Second, scsi_mod means the same as "scsi support" and the latter module means "scsi disk support"; and I WROTE that these are built into the default kernel...OK?
I am waiting for your further but NEW hints,
Cheers,

Thanks alot but I said that where the problem arises. It is not about the "-t vfat" option! It is about this fact kernel cannot attach device as a scsi device; so /dev/sda* refers to nothing.
I am waiting for more technical notes....
Cheers,

Thanks for your reply. I didn't said that Linux application are worse than anything else. Also noting your sentence "I like digikam" or "My canon digital elf s500 works perfectly under linux." has no effect on solving my problem! Your camera is known under libgphoto but mine is not. All the cameras that can act as a usb-mass storge system (like my own camera; don't know yours supports it or not) must accept this funny standard mounting procedure which actually has not worked for me so far....
Great Cheers,

Are you using a 2.6 kernel because it should support most USB devices.

Thanks...
No, I use the default bare.i 2.4.29 kernel which comes with the CD's. It has anything and it's well compiled and it seems ready for any modern hardware...but.....
Cheers,

I was just asking because hardware support is much better in the 2.6 compared to the 2.4 kernel. Anyway good luck, hope you sort out your problem soon.

Do you have hotplug enabled?

--Shade

Did you try sda or sda0?

If I were having this much trouble with my digital camera and usb/scsi modules, I'd try something different. For example:

- the latest version of (lib)gphoto2
- using a memory card and card reader instead of connecting the camera directly to the PC

Thanks for your note...
Yes, of course. As you can see the logs in the dmesg or tail outputs. When I plug it, everything using hotplug loads; but...
Cheers,

Thanks for your note.
It makes no difference which to be used! I have tried ALL of the possibilities. (sd*)
Great Cheers,
