Hi, my usb drive comes up as usb2.0 device, and the modules involved are

So, make sure the modules are loaded and the lsusb shows the appropriate bus.

You may also find that the disk-format/mounting utility in setup may automate this process for you.

Hi,

This is the problem, sometimes the usb appears normally, here is the list now,

Bus 005 Device 002: ID 13fe:1d00 Kingston Technology Company Inc. DataTraveler 2.0 1GB/4GB Flash Drive / Patriot Xporter 4GB Flash Drive
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

How to fix it when the usb doesn't appear ???
in that case the fdisk -l doesn't display the usb drive ??? is it a hard pb ??

thanks for help

Hi, no it is not a hard problem.

It is difficult because i can't see it.

When you have the listing in lsusb, open /etc/mtab

you might find a line like this....
/etc/mtab

Code:

/dev/sdi1 /media/SLAX4GIG vfat rw,nosuid,nodev,uhelper=hal,uid=500,utf8,shortname=mixed 0 0

the corresponding line in fstab, which you can edit/add to....

/etc/fstab

Code:

/dev/sdi1 /media/SLAX4GIG vfat  fat=16,defaults,user,nosuid,auto,umask=000 0 0

see if that helps, regards Glenn
