Hi everybody,
I searched a lot in the community before writing but I didn't find my case.

I'm working with the Lego Mindstorm NXT device. Actually, I'm writing some behavior with Java LeJos and I need to connect my brick to upload my code.

When I connect the brick (USB) I don't have feedback from my computer. The computer doesn't mount the device.

This the output of dmesg:
Code:
[ 3487.972028] usb 4-2: new full speed USB device using uhci_hcd and address 3
[ 3488.148154] usb 4-2: configuration #1 chosen from 1 choice
[ 3847.640054] usb 4-2: USB disconnect, address 3
This the output of fdisk -l:
Code:

And this the output of lsusb:

I don't know what to do.
I just can see the device in the list of usb connected but nothing more. It seems that the system doesn't recognize the device. I'm becoming crazy!!!!
Someone can help me?
