finding a flash drive's device node

[Universal344]

I want to try to install Ubuntu Netbook Remix on a flash drive but I need help writing the img file to the other flash drive first. I found instructions on Ubuntu's site that give me the command but tell me I need to know the device node that the kernel has assigned it. It told me to use dmesg | tail -20 to find it. I was wondering how to interpret the output of Dmesg as I cannot tell what the device node is from output given. Thank you for any help you can provide.
