Invisible USB devices!

[C4lv1n]

I just plugged my usb into my computer, and nothing happened. I'm told that an icon should show up on the desktop but there isn't one. I've also looked at some of the tutorials on how to mount a usb but they all rely on linux actually seeing the usb. Most also want me to know the file type (FAT32, etc) which I also don't know. Help please?

what is the device?

run lsusb command and post back results

if it is usb flash drive or usb hard disk, also post output of sudo fdisk -l

I have no idea what this means

[reed9]

Well, you have an 8 GB drive of some sort in there, formatted to FAT32. Looks like a flash drive to me.

I assume the USB stick you're looking for is 1) the only external drive attached and 2) 8 GB in size?

You usually don't need to specify the filesystem when manually mounting. It's pretty good at recognizing it on its own.

Make a mount point

sudo mkdir /mnt/flash

Mount

sudo mount /dev/sdb1 /mnt/flash

It should automatically create a mountpoint under /media with the device label. Check to make sure that's not happening.

Also, you can plug in the device and check the output of

dmesg | tail

That may give us some more info.

[coopstah13]

if the flash drive is what you are trying to mount, it is being detected

you should be able to just open the file manager and double click on it to get access to the files without having to muck around in the terminal

just open places->computer and you should see it in there, if this is not the case, then refer to reed9's previous post on how to manually mount through the command line

[C4lv1n]

Looks like I'm going with the terminal option. What you said should be there, isn't. It's been the same with a lot of other stuff. Does the netbook remix just suck? Or is it me? (Probably me...)
