If the USB mouse is not working just try rebooting (one or more times). I have a USB mouse and USB ethernet adaptor. I don't think I've ever had them both work after a power up. I have to reboot up to four times before they both work.
I guess I didn't keep good notes. The editable eznet.conf is /tmp/config/eznet.conf (remember to run "freeze" after editing this file)
The "service" entry needs to match the hostname (in configuration - network - configuration). It defaults to "ia1", like the first service line in your file. I'd get rid of the first four lines in your file and change the "1" at the beginning of the remaining lines to "0" (don't know if that's really necessary, but it would then look like mine).
Now on to vim. It basically has two "modes" of operation - Command mode and Edit mode. From what I can tell, there is no way to tell which mode you're in. When you first start it up it is in Command mode. Typing "i" puts you into edit mode to insert. Typing "a" puts you in edit mode to append. Typing "x" will delete the character at the cursor. To get out of edit mode, press cancel. When in command mode, type ":q!" to exit WITHOUT saving. To exit and save, type ":wq"
