Title: USB Block erupters with lots of hardware errors Post by: Legendario on February 19, 2014, 12:30:27 AM I have a Raspberry Pi running bfgminer with an Orico USB hub and 10 USB block erupters attached to it. The problem is that actually only 3 of them work well. The others show lots of hardware errors.
I have tried testing the erupters individually and switching them to see if there was a problem on them or on the hub ports themselves. But they appear to be ok. I'm clueless about what can probably be causing this behavior. Can anyone give me a hint? Thanks in advance.

Most likely a power supply issue. Each block erupter needs ~550 mA. If you have 10 + pi, you are going to need almost 6 amps - which is huge for a USB outlet.

I had to find another power adapter which I did from a OLD Linksys Wireless B Access point which was 5V 2.5Amp which could support 5 BEs and they are happy and mining at full speed and no errors
