halo... I cannot detect my thumb drive in fedora core 2, 2.6.5-1.358 but i can detect the thumb drive in fedora core 4. DId anyone know how to detect and access thumb drive in fedora core 2 ???

Thanks.

Well, I'd like a little more information.

Are the modules loaded? run lsmod and check for sd_mod and any usb module unless you know that these are built into the kernel.

Run lspci to see if anything appears. Check your logs just after connecting it to see if there is any pertainant information.

Post back whatever you find.

halo....

May I know how to check the modules loaded ?

When i typed "lsmod" and "sd_mod" , there are error message shown as below:
"bash: lsmod: command not found "

Is that i have to type any commands before these ??

you should definitely have lsmod. You may have to run it as root. If you truely do not have the lsmod or lspci, you'll need to use whatever package manager you have, and install the pciutils package for your distrobution. This package is generally considered part of the base install though.

--- Edit ---
Those are L's, like LSPCI

Fedora does not setup its path correctly for every user. The utility lsmod is in /sbin. Just type /sbin/lsmod or 'cat /proc/modules' as a user. You do not need to use root to get a list of loaded modules (drivers).

The modules that are needed to access a usb storage media are usb-storage and sd_mod assuming USB modules are already loaded.

It takes a few tries to get Linux to register USB storage.

i typed " /sbin/lsmod " in terminal and it shown :

But i still cannot detect my thumb drive after typing "/sbin/lsmod" few times.
Did you know why ??

The modules look good to me. Once you've plugged in the usb drive, wait 5 seconds and type dmesg. It should give you the /dev/sd_ that the usb drive was attached to. From there you can mount it and access the files.

halo... i did tried to typed "dmesg", and it shown as below:

It shown that the thumb drive usb storage is at scsi0 , but i cannot find the location of it. Did you have any ideas about this ??

halo.... i did able to mount my thumb drive according to this link:
http://www.linuxquestions.org/questi...d.php?t=284453

Thanks to your advices. May I know should i unmount it before plug out my thumb drive???

If yes, how to unmount it ?

musicman_ace,

Love your tagline!

Just reformatted my USB drive to FAT32, but it is still read-only. How do you recommend I fix this?

Vin¢

musicman_ace,

Thanks for posting this - exactly what I needed.
Q: After reformatting my USB drive to FAT32, it is still read-only. How do you recommend I remedy this?

Thanks,
Vin¢

Unless you specify readonly, it should be mounted read/write. As for unmounting, it should be umount /dev/sda assuming it is sda

Any storage medium except floppies need to have a partition. If you do not put a partition, you will not see the data next time you use the device.

To mount FAT32, include umask=000 option. For an example, 'mount -t vfat -o umask=000 /dev/sda1 /mnt/media'. In some cases, you may need to specify rw or 'mount -t vfat -o umask=000,rw /dev/sda1 /mnt/media'. Though you may need to set rwx permissions to the directory where you mounted after mounting, but you only need to do it once.

I recommend do not put a line for USB/IEEE-1394 storage devices in /etc/fstab. These devices changes a lot and the line in the fstab file for these devices will create headaches. I recommend either mounting them manually, setting up hotplug to mount it, or set up udev to mount it.

Electro,

Thank you for your post. I genuinely appreciate the time you put in.

I'm sure that's all good advice, but I've been a Linux man for all of 6 months, and can't make head or tail of what any of it is supposed to mean. -Incidentally, I tried it, and no go.

I need to know how to set permission for the /dev/FlashDrive THAT STICK, and possibly, if that doesn't work, the specific cl syntax for setting fire to the machine while I'm at work, so the insurance comes through.

Gotta tell ya, after Windows, I need GNU cl to be learnable, or I may as well hitch a train out to Iowa and take up grass farming. Maybe too many NuBs are too shy to say this, but I KNOW NOTHING, and am at the mercy of every kind soul that posts here. (Any of you who find yourself in Indy, please let me buy you a beer or ten.)

Vin¢
