I might see what Microcenter has before going to Best Buy. I originally wanted one of the Ankers but I was unable to find one that would arrive around the receipt of my erupters. I hoped the Juiced hub would at least get me 90% uptime until I decided to expand or invest in something else. The worst part is sitting on ASIC devices that I cannot put to work == losing BTC 

I purchased 6 USB erupters recently and went with the Juiced Systems USB 3.0 / 2.0 - 13 port USB HUB:


http://www.amazon.com/Juiced-Systems-USB-3-0-2-0/dp/B00B1WMYGO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1376614790&sr=1-1&keywords=Juiced+Systems+USB+3.0+%2F+2.0+-+13+port+USB+HUB+5v+Power+Adapter

 A 3A adapter is included and I only planned on running 6 erupters in the short term, so I figured this would be a hub well matched for my setup. When I first had it connected and running there were no problems or hardware errors. The setup ran steady at 2 GH/s for a day or so before one of the devices starting giving continuous ICA invalid nonce errors. I restarted cgminer and was immediately flooded with errors for the same device. I moved the USBs around, rebooted, etc etc and can't get the hub to work with 6 erupters at this point.

So I started running 5 erupters... after about a day the same damn thing happens except cgminer is complaining about 2 of the 5 erupters. I restart cgminer with just 3 erupters connected, and I get these errors:

[2013-08-15 20:45:54] Icarus Detect: Test failed at /dev/ttyUSB0: get ffffffff,
 should: 000187a2

[2013-08-15 20:46:46] Icarus Detect: Test failed at /dev/ttyUSB1: get 00000000,
 should: 000187a2

Sometimes the host is seeing 0000000 for 2 of the erupters, sometimes FFFFFFFF, sometimes 1 and 1 as shown above. Sometimes it will start without error codes, but give the continuous invalid nonce errors after a few seconds of operation. At this point I can only reliably run 1 USB erupter in my fresh Ubuntu host with cgminer 3.1.1 (compiled with icarus support of course) and the latest version of bfgminer. All devices are linked in /dev. I have also tried my Windows 7 host with proper drivers and cgminer 3.1.1 with the SAME result. In the Windows host, all devices are assigned a COM address and any single erupter will work, but with 2+ connected through the Juice hub it will either give the 'get 00000000' error or loop into the invalid nonce sequence.

I guess I'll be off to Best Buy in the morning to find a random powered hub to try out.

I would like to be whitelisted. I have been a lurker for a long, long time and am interested in a buying a handful of the erupter USBs at the current .45 btc price. I began mining in mid-2011 when bitcoins were fluctuating around 3.00 USD, I was mining with a 6870 and 57xx for a total of 500 MH/s and got 1 BTC every 18 hours. I sold off when BTC hit 30.00 USD for a fair profit but BTC quickly tanked so I sold my cards and got out of it for a while. If only I had stayed with it.....
