i downloaded bfgminer gen2, im using 2 block erupters on windows 32. the problem is the very low shares acepted, 1 or 2 shares every 5 min. what could be the problem?
If u have low reject rate, i think the problem is the DIFF of pool.
Post ur conf.

http://i58.tinypic.com/11rx3yh.jpglittle story:
I plugged 5 USB Erupters to hub and connected to ibipot.com pool.. hashrate was 600-700MHash/S total.. :O
disconnected USB's one-by-one..
finally figured out that PC has Atom CPU and was not able to perform scrypt fast enough..
Mainly when hash is low I have figured there is some kind of PC CPU limit reached.. - bottelneck CPU
For example on other i7 CPU PC my college runs cgminer-med(1st) + MCProxy3 + stratum-mining-proxy (latest posted here) he has BFL Jalapenos total has 12.5G but cgminer only shows 9-10MHash.. limiting factor on his PC is stratum-mining-proxy that appears to be single threaded (not using all CPU cores) - bottleneck CPU and proxy software
I recomend we should identify our bottlenecks and write here, so developers can develop better software

I also keep an eye on pool server, but there are lots of resources available..
EDIT: I also run 3x Antminer U1's under MacOSX, using standard bfgminer, then I run windows 8.1 (90day demo) virtualbox on the same Mac and there I use latest bfgminer-med with --http-port option connected to pool. Hasrate is 4.46 that is what it should be.. - no bottelneck, Mac CPU can handel all and I still can work at the same time.
i changed my 2 erupters to a core i3 laptop and still same results. i thought my little atom was the problem but now using a bigger CPU and still a few accepted shares per hour.
