I have installed Win7 64-bit (perhaps a mistake) on my system previously running XP.
Previously, LPCXpresso worked fine.   Now I cannot get the connection to
the LPCXpresso pod to work properly.     I am working with a 1114/301.

I have followed the diagnostic here;
http://support.code-red-tech.com/CodeRedWiki/LPCLinkDiagnostics

When I plug the pod in I see "USB Device with DFU Capabilities" using
Device Manager.   When I execute "bootLPCXpresso hid" the DFU device
disappears and two new devices appear in "Human Interface Devices".  
The new devices are "HID-compliant device" and "USB Input Device".
Hewever these new devices do not appear to be the LPCXpresso judging
from the hardware ID's.   It seems that the LPCXpresso has disappeared!

If I unplug it the above cycle repears.   I never see LPC-Link as I did
with XP.

Is there anything that I can do?

Thanks,
Pete.

Under xp it is booted as a winusb device but under win7 it is booted as a hid device, so you will find it under hid devices. There is a preference for changing this. Afaik it is done like this for performance reasons as the xp hid device driver is c***.

I solved the problem.   My fault.   When I installed Win7 I also installed a clean copy of LPCXpresso V4.1.0_190 and CMSISv2p00_LPC11xx which got me a new system_LPC11xx.c file.   This contains;

[COLOR=#3f7f5f][COLOR=#3f7f5f]#define SYSPLLCLKSEL_Val      0x00000001[/COLOR][/COLOR]

[COLOR=#3f7f5f][COLOR=#3f7f5f][COLOR=black]which selects an extrnal oscillator.   I am using the internal oscillator so this causes [/COLOR][COLOR=black]a hang in the wait until PLL locked loop.   I had fixed this in my old environment but [/COLOR][COLOR=#000000]the new environment killed me.   So this was my fault.[/COLOR][/COLOR][/COLOR]



[COLOR=#000000]What threw me was that under XP the LPC pod appears as "LPC Link" in device manager when LPCXpresso had initialized the pod.   Under Win7 it just disappears after initialization![/COLOR]

Win7 64-bit works OK here.

What happens when you let LPCXpresso do its own booting? If there is a problem it gives you the option to display the log. What does that show you?
