ANTMINER U1 Hashrate on Raspberry Pi Wheezy

[miroman86]

Some of my Antminers aren't giving out the same hash rate as the others... What do the three columns about my hashrate are? There are three columns, and if you can see, AMU3 AMU5 and AMU9 are really low on the 3rd columns... I'm using the latest BFGminer...

Why is it like this? Any fix?

Probably not getting enough power to those miners.  Try switching the low ones to a different usb port, and see if it is the actual port, or the miner itself.

Unless I am mistaken, the third column is the total average hashrate for that device. The current hashrate is correct, it probably because you unplugged them and plugged them in, but left some time without them mining. Try restarting the miner, then all averages should be about the same.

I just got some new D-Link 7-port hubs, heard they're great for these USB ASIC miners... Even up to 6 miners on 1 hub (from the forums)... I currently have 2 hubs daisychained, total of 10 miners, and then the hub with 6 miners, I plugged directly to the RPI.

I ran them on a Mac before, but on the Anker USB3.0 9-Port+1chargingport hub... They ran kind of faster, but I wasn't able to tell since the interface on MacMiner is different, I didn't see any of those 3 columns of hashrates...

Power? or defective miner?

Thanks! I will try this later when I get home. Most of the time when I restart it though, it doesnt detect one of the miners, it only detects 15... If I restart my Raspberry Pi, it detects them all... But it gives me those 3 low hashing ones.

I use the same hubs.  When I plug into either of the 2 "extra power" black ports, I either dont get the miner recognized, or it is slow.  Keep that in mind, not sure why it happens

Thank you! Will keep this in mind... I bought 4 because I really didn't want to put in 6 miners in one hub, hopefully it works when I switch it around. I thought at least if I had 6 in one hub it wouldn't give me problems.

Have you tried connecting any USB 3.0 hubs into these Dlinks and make it work on Raspberry Pi?

I do not have a RaspPi, so no, I have not.
