Connected my new LPC-H2148 up to a falcon and plugged it into the usb on my pc, new hardware wizard pops up and i directed it to the custom.inf in the nanpro folder. Message pops up telling me the new hardware has been installed so i open a command prompt and type

c:\nandpro-20b\nandpro.exe usb: -r16 orig.bin

and i get the message

Looking for usb interface
No device found
Can not continue

Any ideas chaps?

OK sorted it. just me being stoopid. Messing around trying different usb ports i had installed it and then switched usb ports so when i went into device manager i had 2 memory access's and one had the yellow exclamation so reinstalled the custom inf to that and it flies now
