Lexar JumpDrive Sport 128MB and CentOS 4.0

linux-rulz · 04-06-2005, 02:25 AM

Hey.

I am having trouble with my Lexar Flash Drive and CentOS 4.0 (essentially Red Hat Enterprise Linux 4.0). I plugged it in the first time and Gnome auto-mounted it. However, I cannot get it to mount anymore. Knoppix loads it fine.

Does anyone else have any ideas?

Thx

Have you tried mounting /dev/sda1? Unless you have SCSI drives on your system, a USB HDD or thumbdrive will often shows up as that device. Just do:

Code:

# cd /mount
# mkdir jumpdrive
# mount /dev/sda1 ./jumpdrive

When you plug it on, typing in 'dmesg' will show you the exact location of the drive (sda, sdb, sdc, etc) then you can mount it the way imemyself mentioned. Something else you might want to do is add the following line to your /etc/fstab file:

Code:

/dev/sda1 /mnt/sda1   vfat   noauto,users,exec,owner,umask=000  0 0

"/dev/sda1" is the target device, change it to whatever yours is listed as

"/mnt/sda1" is where the drive will be mounted, you can change it to wherever you want it mounted (such as /home/user/jumpdrive) just make sure the directory you choose exists (mkdir /your/directory)

"vfat" this is the filesystem type, 10 to 1 its going to be a fat filesystem

"noauto,users,exec,owner,umask=000 0 0" this lets your computer know the permissions of the drive, along with how it is mounted. 'noauto' means you manually mount it, you can change this to 'auto' and it will try to mount on each boot. Using this layout will let you have full read/write abilities on the drive.

Once you have that all taken care of, save the file. Now simply typing in '$mount /dev/sd*' will mount it to the directory you specified.

Sorry, I should have posted more info. I tried /dev/sda1 and /dev/uba1. Also, when I try /sbin/lsusb, it doesn't show up. It works fine on Knoppix. I even tried rebooting while it was in the computer and it won't work.

Did you try 'dmesg' to see where it is located yet?

This is the output from dmesg

usb 1-6: new high speed USB device using address 5
usb 1-6: control timeout on ep0out
usb 1-6: device not accepting address 5, error -71

Okay, something is preventing it form assigning /dev/sda1, etc. Have you tried it in another usb port? The only other thing I can think of is making sure usb plug and play support is enabled in your bios, but you said it works in knoppix, so it must be on.
