With 85-code-red.rules installed, LPC-Link will be automatically booted and made world-write (meaning that you do not need to be root to access it). This explain
1. why dfu-util reports no DFU device - becuase it has already been booted
2. why libusb reports
Bus 002 Device 007: ID 1fc9:0009 NXP Semiconductors
this is a booted LPC-Link
When 85-code-red.rules is copied into the rules directory, you either need to reboot, or restart the udev service. So just copying the file will have no affect.
There should never be any need to reinstall LPCXpresso, unless any parts of the installation have been changed.
We do plan to release the udev rules in a future release of LPCXpresso.
Thanks for the feedback guys, but if you look through the text files I attached you'll see my comments saying I did several types of poweroff/reboot/restart operations on the machine and the system continued to fail (with the new rules file in place). So unless I explicitly need to do this before I run LPCXpresso my feeling is there's still something unknown here. I'm not saying you're wrong, just that my environment is subtly different from yours.
