Jalapeño+RPi lower hashrate than with CPU

[ZKRiNG]

Yesterday arrive my jalapeño, and i try to use it with my previously prepared Arch Linux with bfgminer, and put it for mining and leave it alone.

When i back home, i seen it still saying 4-5Ghz, but on the pool website just say 2,6Ghz. Try with Easy Miner of bflabs on the computer and its mining always at 5,3-5,7 Ghz.
Why?
Its needed USB Hub for just 1 jalapeño? Any suggestion?


Thanks

Try a different pool. Also use stratum if you aren't already.

Now i compile cfgminer and its works perfectly.

Will try using stratum too. Now i need more changes like put some scripts i found on some forums looking for answers about the problem. For auto-reconnect and will be perfect if i can put on the pi a wifi usb and put on different room.
Its too loud for a a sleep room and i have so much problems for sleep just with the typical house sound, with the Jalapeno will be impossible rest.

Really thanks Beastlymac
