Hey, I got a problem with my 16GB Verbatim USB-Stick.
it used to work perfectly but suddenly no pc can detect that USB-Stick, no matter which OS, except the ones that are connected to out school network.
It also happened right after connecting it to one of the school PCs.
Is it some kind of virus?
If so, how do I get red of it?
Please help me!

And I didn't format it
And I use linux

I'm fairly sure the "Trust international" one is relating to a bluetooth adapter, since I saw that when googling it, and bluetooth was pasted all over your dmesg. Do you have any other USB devices in? Try removing the drive and doing lsusb again. If an entry disappears, then the devices is registering with the system, at the very least.

Strange, I do not see any trace of your USB drive. Or the usb connection of the usb drive has some corrosion .. or it's broken
(Or it was not in your computer when you ran dmesg )

Oh, that is very strange.
Do you have to problem in more than one computer?

Sorry, I misread your first post.
It is very strange that you only can view the content of your USB drive in school.
And I do not see any trace of it in dmesg.

Can it be you physically damaged the usb plug a bit, making that only the PC's in your school can read it (because of different usb sockets the computer have)?

WOW, what is going on?
I had the stick all the time in and suddenly it is recognized! *yay*
let's see what happens if I deplug and replug it...
EDIT: It works now normal on my pc, maybe linux fixed it
