Want to demo mining to kids for educational purposes (plz dont spam on its not worth mining with old rigs bla bla - this is a tech issue, i don't really need to mine a block):
I setup latest bitcoin core 14.2 full node on a win7x64 machine with correct bitcoin.conf settings for solo mining (tested with bitcoin-cli)
I setup latest 5.4.2 bfg miner (64bit)
I plugged in my old BFL jalapeno ASIC box (dusted it off) - win7 installed drivers automatically from win update correctly (COM14).
ran BFGMiner (according to BFGMiner readme example for solo mining):
bfgminer -o

BFG finds pool and authenticates correctly, but it has trouble connecting to the Jalapeno com port 14:

[also tried to GPU mine - my comp crashed, last resort will be cpu mining but i need to recompile your code for that...]
Any suggestions ?
Thanks
