Hi Tom,
   
  My hardware is so strange !
   
  In anex the schematic in pdf.
   
  Five times in hundred of tries, it works.
  I could install the driver and using Hyperterminal I could transmit/receive by virtual com serial (COM3 was used).
   
  At most time the hardware is not recognize. And sometimes it works !.
   
  What is happening ?
   
  When the hardware is working if it´s not unplugged, it´s work indefinitely. But, after unplugged, it doesn´t work after re-plugged.
   
  thanks,
   
  Maia.

  Maia,
    I suspect that your firmware is not running. Can you 
reprogram the flash and use a known, good HID example to
test first?
    Yes, it's important that, your PID and VID should match
between these in the descriptor table of the firmware and 
host driver INF file. The mismatch in the PID and VID area was 
the only installtion issue people complained about long time 
ago. Since then, I've not heard of any installation issues.
    Uninstall the VCOM drivers, have a clean start, once you
plug in the USB cable, the window device manager should pop out
automatically and ask for host driver info. If not, something
is wrong in the firmware already.
    A very effective way to debug the firmware is, add external
power +5V on VIN of the Keil MCB2140 board, program the flash, 
start the debugger, set to run, unplug and replug the USB cable,
then you can single step to debug.
    Check the device manager, if there are some drivers installed
under "Others" area, check what they are, uninstall them, 
minimize the number of USB connections first, just for testing
purposes. 
    The two OS platforms we tested are W2K and XP. What's yours?

Regards,
Tom
