[K12OSN] Some issues using USB sticks

[Meelis Mihhailov]

Hi Jimmy!

I belive those names are not identical. One user is our library worker and 
the other is customer. They just happened to have same Kingston models. :) 
Our workers' USB stick worked well but customers' USB stick did not. Now 
it's hard to get the name of the customers' kingston usb stick as he/she is 
at home and I have no idea if this person visits us this week.

So the theory may be conflict between USB sticks by their names? It might be 
so if thay are both used at the same time but while testing they were used 
separatelly so at the server side one USB stick session had to be ended 
before another one opened ... there could not be a name issue ... or I'm 
wrong? I tested it by phone and ssh session with the server. I was not at 
the room.

Could this be a matter of USB port on the client or somekind of partition 
table on the USB stick that is not understandable by LINUX?
