Lpc2000

Thanks a ton bertrik.

i want one more info. we have a CON bit responsible for current connection
status. so, in a situation where,

a) we initialize the USB for the first time,
b) but the board is not connected to any USB host

will this CON bit tell us that no connection is there?

Thanks again.

Regards
Manisha

I wrote a USB driver for the lpc214x so I'm quite familiar with the
specifications of the USB controller, but I have not seen any register
to read the current the configuration status.
