how should i connect the usb drive to the calculator?
i have an usb hub with power cable can i use this

can somebody help me i cant use ubuntu to copy the data to the usb and i cant us e kali linux cause at ubuntu you dont have the permissions to copy at the usb cause you dont have an root account and in kali linuxyou dont have an untar programm and the command you gave me causes an error 

root@kali:~# tar -xvzf xconfig.tar.bz2 -C /dev/sdd
tar (child): xconfig.tar.bz2: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
the usb drive is ext4 formatted

To your first part of your double post:

xconfig.tar.bz2: Cannot open: No such file or directory

To extract a file, you need to have to file to extract first.

to the second part:

if i connect the usb to my calculator and type df the usb isnt listed there

"lssci" maybe. Or "lsusb". For "df" the usb drive has to be mounted first.

ok with xjvf i got it extracted at the desktop but if i copy all the files to the usb there is an other error but i think all the files are copied

ok i think my calculator sees the usb device this is what he gave me after typing dmesg
the picture is in the attachements
ill ty to format it ext3 and try it again

and i cant boot xconfig from my usb drive :s what format does the usb needs to be ext2/3/4?
