I'm trying to get Raspbian to recognize a USB memory stick. Simonsmall wrote recently:

This shows the "devices" that the hardware knows about, in this case the parts of the SD Card that NOOBS created.

Now, plug in the thumb drive into a USB socket. Type the same thing again.

pi@raspberrypi ~ $ ls -laF /dev/disk/by-uuid/

There is a 'new' line that shows what the thumb drive has been called, in this case "sda1")
****************
Trouble is, in my case there is no new line with sda1 or anything else. The output is identical both times. What is wrong? I have files on the memory stick I want to use on the Pi (tar files). How do I get Raspbian to "see" the memory stick so I can hook it into the file structure? (Yes, I'm a complete newbie...)

This looks like a problem with your memory stick. You should really start a new thread for that [edit]That's been fixed. Ta.[/edit]

However, try this to see if your stick is even recognised:

1. Plug in your stick.
2. Wait about 5 seconds
3. Type: "dmesg | tail -20l"
4. Post the output.

You should see something like:

Code: Select all

Ignore the first few lines. It's the bit from "new high-speed USB device" onwards that are important.

It is a pity that you did not read the last post on that thread - it is from back in June, and there was a problem where two people were asking different questions and everyone got confused.

It would help us a lot if you could copy your post into a new thread, then post a link to that thread in this one. That will make the answers you get a lot clearer.
