OK thanks, at time I have no problem, but when also hang my Raspberry on the HUB then i have a problem with port 14!? Good day, I have a problem with one BFx2 Miner, one miner always lose the "red light" at one USB Port "14" and run very slow, is this a problem fro the USB port or to less power from the port? The miner runs but without the "Vcore" light!??? cgminer version 4.3.3 - Started: [2014-05-20 18:55:35]

-------------------------------------------------------------------------------- regards So i don't know... Try this: Swap your PI cable from port 19 with the miner on port 14, that will take your USB chain to the miner down 1 level, it will also highlight if it is a socket problem on 14 RF |

@klintay I have received the HUB yesterday, unfortunately I had to pay extra for 30 € customs fee ... So the HUB run with 8 BiFury Miners and 10 Antminer U2+, I hope he is strong enough for the load!? I load pictures tonight  regards Should be no problem. This hub can support all those miners, even if it is fully loaded. I have sixteen twin chip miners running nice (average speed is 3.8 gh/s per miner, without overclock) OK thanks,
at time I have no problem, but when also hang my Raspberry on the HUB then i have a problem with port 14!?
Try plugging the miner into another port on the hub and even directly into a computer by itself. If the voltage light is still turning off then it could be a defective miner and hence it needs replacing. Who did you buy BFx2 from? Maybe they can replace if it is not working as it should. Also is the raspberry pi always hanging? So my pictures of the HUB with the miners: regards Nice setup by the way |

Good day, i switch the Bx2 miner amog themselve, but only at port 14 has problems!? At time it runs good, the Pi have an extra power supply On evening i will test it again... Yes an the raspberry pi is always on to monitor my photovoltaic plant. greets |

This sounds silly but change miners around so that antminer is in port 14 instead. |

Hello, at time all run good on port 14 (But two BFx2 miner run slower and I'dont know), so i have order a xtar USB detector a will test each port and will report you  regards |

Hello, at time all run good on port 14 (But two BFx2 miner run slower and I'dont know), so i have order a xtar USB detector a will test each port and will report you regards Luckily it's only $5us There is an 'inherent flaw' in such devices, some require to feed the target device via a low value resistor and then compute the voltage drop across the resistor. ( in doing so they drop the voltage but also have to pass ALL the current from the measured device thru the measuring resistor…) So don't take the results it gives too seriously , it unlikely to report the details correctly & it may stand a good chance of slowing the miner down a little (due to current limitation)( But it may reduce the number of HW errors you get!!!!) Also do not leave it plugged into the port permanently as it is likely to overheat & distort the plastic case. There are better units available that do not use such limited ways to measure the current. RF |

Hello guys, so I have test a little bit he HUB, and I think it’s a good quality Only the voltage is on the lower end of the USB standard. My Devices: 10 x Antminer U2+ (~ 1,8 GH/s / anu-freq:225), 8 x Bfx2 (~ 3,5 GH/s / bxm-bits:53) Here my table: | USB port | Device | Voltage | amperage | | 1 | Bfx2 | 4,45 | 1,01 | | 2 | Antminer | 4,55 | 0,61 | | 3 | Bfx2 | 4,40 | 1,05 | | 4 | Antminer | 4,50 | 0,62 | | 5 | Antminer | 4,60 | 0,64 | | 6 | Bfx2 | 4,40 | 1,05 | | 7 | Antminer | 4,60 | 0,64 | | 8 | Bfx2 | 4,45 | 1,02 | | 9 | Bfx2 | 4,45 | 1,07 | | 10 | Antminer | 4,60 | 0,61 | | 11 | Bfx2 | 4,45 | 1,01 | | 12 | Antminer | 4,55 | 0,61 | | 13 | Antminer | 4,65 | 0,59 | | 14 | Bfx2 | 4,45 | 1,07 | | 15 | Antminer | 4,65 | 0,58 | | 16 | Bfx2 | 4,61 | 1,01 | | 17 | Antminer | 4,55 | 0,61 | | 18 | Antminer | 4,50 | 0,61 | | 19 | Empty for Pi later | |

Hello, i know it's a cheap comparative and no measurement, but on a other Power Supply ( Solo 1,5A@5V) is the measurement with the USB about 4,95V. It should also be noted tolerances:  For my purposes, it was sufficient that I've seen that it can not be due to the current strength. When comparing the one should also note that the ~ 4.5V were measured at load in idle it was at ~ 4.85 V. regards |

I have made a nice unboxing of the Eyeboot.com usb hub. Reading all the reports abot the voltage, my Chinese voltmeter says 5.023 volts on usb port 1. Maybe inside you can easy lower of increase the voltage? Bit off topic, the usb hub really turbo charging my mobile phone  My Unboxing video, please thumbs up :-)http://youtu.be/oPESQzCq8L0 |

Will this work for charge and sync¿?
Basically my usage will be a Little bit different that bitcoint miner, we need to use as a charging and sync station.
I know the total AMP for both of them
10 port [10amp] =
• 5 devices of 1.0a (Charge & Sync)
• 2 tablets of 2.1a (Charge & Sync)
• Total load 9.2amp
¿Am I right?
19 port [20amp] =
• 9 devices of 1.0a (Charge & Sync)
• 5 tablets of 2.1a (Charge & Sync)
• Total load 19.5amp
¿Am I right?
49 port [75amp] =
• 38 devices of 1.0a (Charge & Sync)
• 15 tablets of 2.1a (Charge & Sync)
• total load 70.5amp
¿Am I right?
In resume, is the AMP measure by usb port or by total load?. Could I buy a 100amp 5v PSU for the 49 USB port? In order to supply 2.1a to all of the ports

The 19 port hub can only do a maximum of about 1-1.2 amps per port. price drop to $60 usd |
