[K12OSN] Some issues using USB sticks

I have a strange problem with USB sticks with my server and terminals.

At the moment I have two users with USB sticks. One of them connects it to 
the terminal and server shows the user a folder that is users' USB drive. 
Now when a second user connects the USB nothing happens.

Both USB sticks are Kingston 128Mb.

Do I really have to ask every user their usb device information in order to 
make the server understan each USB stick? (install drivers) or is there 
another solution?

Here is the log :

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Nov 26 16:12:35 5k_terminal5.ltsp root: udev detected remove of floppy
Nov 26 16:12:51 5k_terminal5.ltsp root: udev detected add of disk
Nov 26 16:13:00 5k_terminal5.ltsp root: udev detected remove of disk
Nov 26 16:13:00 5k_terminal5.ltsp root: udev detected remove of floppy

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////


As we can see ... first detection is not shown in the log. It's as nothing 
is connected by the user so the server cannot understand if there is an USB 
stick present. However when this user removes the stick suddenly log shows 
that it detected the removal of this magical device.
When the second user connects on the same machine USB stick (not the same!) 
then everything works like a charm.

Is there any help or reading that can be done in order to ease this problem? 
I have public access terminals (around 50) with random users and it may get 
ugly if number of unhappy users start to riot :)

Thanks!
