I have been working with the XEM6001 for a while, working fine.
I switched to a xem6010-lx150, made a new bit file which seems to work when loaded with JTAG, of course I cant see if the OK-HOST or frontpanel works by this means.
When I plug the 6010 into the computer device manager shows its existance as a lx150 front panel device.
But when I tried running my own code, or the samples provided, it fails to initialize. and asks me if there is a board plugged in.
