I've found it useful to have tail running on the messages log in a
terminal window if I'm having trouble accessing a USB device. This has
helped a lot when trouble-shooting USB serial adapters and also when
discovering and reporting a USB mass-storage bug which prevented my
laptop from seeing both the built-in memory and an SD-card in a Medion
S.3747 PNA when it was connected to the laptop via USB.

Just run "sudo tail -f /var/log/messages" in the terminal window. Kill
tail with Ctrl-C when you've finished using it.
