Lpc2000

Without enough description of your problem, here are a few things 
you can try:

(1) Try something you know is working first, e.g. USB HID examples
from Keil.
 
(2) After programming the flash, unplug the JTAG connector, 
then reboot the board again.

(3) Maybe, the host driver is in a unknown state, uninstalled
the host driver, reboot the board, it'll ask for the driver
again. You use the steps I described in the previous msg.
to reinstall.

(4) Reboot the PC.

(5) Check the board jumper setting.
