Hi All,

Total newbie to this device and have stumbled already in the changing room - let alone the first hurdle..... Can anyone please help?

Have the LPC4357 dev kit, a USB cable, and a ULINK2 device. I wanted to try some of the demo examples and get a feel.  Final aim is to re-write lots of legacy Freescale MC68300 code to this device.

Am running, WinXP, Keil 4.74 uVision, and have downloaded code, drivers and examples from Element14. Plugging board into a USB port on laptop prompts for driver-install, as expected. INF file provided did not work ('device driver not found') - the lpc18xx-vcom.inf contained a link to an 'unknown' device

[DeviceList]
%DESCRIPTION%=LPC18xxUSB, USB\VID_1FC9&PID_2002/ABCD
-->
[DeviceList]
%DESCRIPTION%=LPC18xxUSB, USB\VID_1FC9&PID_000C

I changed this line, device driver then loaded .... but still a problem, as get a 'CODE 10' - device cannot start.

Anyone got any good ideas? I have tried several laptops - same problem.

Cheers,
Manny
