On a terminal, do the following:
ps aux | grep -i <exe_name>
Substitute the name of the VNC server executable. If this shows 
anything apart from the grep command, the server is running. ("aux" 
is just my favourite set of ps options that will display the name - 
any set that displays the name is fine.) Alternatively, you can 
locate the start script in /etc/init.d and see if it supports the 
status parameter.

The idea is to use the internal to switch to a vterm and the USB to 
switch back to X to see whether the problem is restricted to X. Just 
typing in the vterm isn't going to work as that works even under X, 
as far as I understood you.

Were there any kernel/X server updates that came in after you 
rebooted the last time the problem didn't occur? Are there any very 
recent backups of /etc/X11/xorg.conf in /etc/X11? Does 
/etc/X11/xorg.conf suddenly contain some weird entry that only 
affects the USB keyboard?

Oh, and: have you tried searching launchpad for bugreports related to 
the VNC server?
