Issue updating Cerb40 (first gen) firmware

Trying to get a Cerb40 up to date on firmware with the latest SDK release. Tinybooter updated just fine using the STDFU Tester but the device is now showing unrecognized on USB and does not appear when using FEZ Config. Does FEZ Config work with this board, or do I have to do it old school (link to the ‘old way’ would be helpful)?

It should work fine but first it has to show in the device manager.

Thanks Gus. I was busted by a bad cable… BTW, first time I’ve used the new FEZ Config - very slick :clap:
