each device will need to be researched, depending on the type.
the devices you listed above will most likely appear as scsi drives like:
/dev/sda1
/dev/sdb1
you will need to make the appropriate entries in your fstab then mount them.
for example a usb thumb drive is setup by the following:
/dev/sda1 /mnt/usbstick vfat user,noauto,umask=0 0 0
then you would type mount /dev/sda1
when you plug in a usb device look at your system logs, if you have hotplug usb support enabled then you will see messages telling you a device was found and what is is called

Finlay,

Thanx for the reply. I installed a little program called "usbview", and it sees the flash drive, but I cannot access it. I figured out how to read my digital camera, but not luck with my flash drive.

What happened when you tried to mount the flash drive? What is it's /dev name? Is there an entry for it in /etc/fstab?

This is what I have on /etc/fstab:
/dev/sda1 /mnt/usbstick vfat user,noauto,umask=0 0 0
then I try to mount it on /mnt/usbstick, and I get this:
mount: special device /dev/sda1 does not exist

By the way I am using Mandrake 10.0

This is what the /var/log/messages says about the flash drive:

Jul 20 10:09:17 localhost kernel: usb 4-5: USB disconnect, address 8
Jul 20 10:09:23 localhost kernel: usb 4-5: new high speed USB device using address 12

Fujifilm Model: USB Drive is my usb flash drive.

Thanx,
Rax

Finlay,

I tried the URL instructions, but still I cannot read my flash drive. I am using Mandrake 10.0
I was able to make my Sony digital camera to work, no problem with it, but no luck with my flash drive.

Linux is getting closer to be a truly P&P OS, but little details like this will keep Bill Gates getting reacher and reacher! There is not question about the Linux is a great super great OS, better than Win98, and 2000.

as i have never used mandrake i can't say this for sure but it appears as though you are missing usb-uhci and usbcore modules.

you may want to move this to the mandrake forum and see if one of them can help you from here.

I do know that slackware and red hat load these modules out of the box.

Problem Partially Solved!

Well, I followed the instructions posted on this site:
http://www.extremetech.com/article2/...1256701,00.asp
I tweaked it a little bit, this site said to use "sda1", so I used "sda" only, and it worked. The next step that I would like to solve is that when I plug the flasd drive, the computer does not see it, I need to munt it, then it's ready. Any idea how to to dos this?
