Difference: AMC13DebugLog (130 vs. 131)

While installing LabTools (impact, chipscope, etc.). There was a problem getting teh Xilinx USB Cable to work. Tried typical troubleshoot suggested in Xilinx forums including manual install scripts. But the Cable was not working (power light should turn on when plugged in while drivers installed correctly and permission set correctly).

The eventual problem ended up being this (courtesy of Jeroen Hegeman):

The problem was as usual in a detail: in the USB settings file deployed by Xilinx here

/etc/udev/rules.d/xusbdfwu.rules

an environment variable name was spelled in capitals instead of lower-case: $TEMPFILE instead of $tmpfile. Took me a while to find that again.
