Particularly, convenient with a laptop, or just to facilitate the insertion and removal of USB cable, a USB 3.0 hub powered by its own power supply is very convenient. After some research, I researched theP10-U3 Orico , hub features 10 ports all independently powered and usable.
The P10-U3 is a hub made of plastic where each USB port is powered by the same level of electrical current. A switch is included and controls the entire power supply to the product. The power supply is included and a USB 3.0 cable is included.
Each USB port comes with a small blue LED to indicate whether a device is plugged in or not.
- 10-Port USB 3.0 Hub
- Compatible with USB 2.0 and 1.1
- Powered by its own current
- 12V and 4A power supply (total of 48W, or 4.8W per port)
Once connected to a computer, everything works and activates without driver or problem. But this type of hub is normally used to extend the possibilities of a computer. By plugging in a very fast USB 3.0 flash drive, the Kingston HyperX 64GB, and testing it fast with Quick Bench I noticed no slowdown.
The side of the charging device, with 4A you may think it could almost charge 2 iPads simultaneously (these require 2.1A each), but no! The device is not designed to allocate 2A to a single port. You can plug in an iPhone to charge it, but no more energy-consuming devices.
It can connect more than one cell, but the total energy will not allow a fast recharging because part of the energy is reserved for unused ports.
On the level of the quality of assembly, I had some problems to insert USB cables at the allcitycodes. It is as if the case was not completely aligned with the ports and the insertion was very difficult. After a few connections, the whole thing was placed.
The blue LED is convenient, but since there is a lot of light leakage, when one LED lights up, the others on each side are also illuminated. Better encapsulation of each LED would have avoided this problem.
What about mining?
From this side, pair to a Mac or PC, no problem! You can connect 10 USB DualMiner and get a total of about 700 KH / s. For Bitcoin USB minors, you will have difficulty connecting more than 2 of these devices since the latest models require between 1.5 and 2.8A each.
Update. To use this dock with a Raspberry Pi, make sure to configure Linux to use it in USB 1.1 mode, otherwise connected devices will not be recognized. Update the cmdline.txt file and add this on the same line:
1 dwc_otg. speed=1
Then you have to restart the RPi. But before going too far, be sure to connect only the dock to the RPi before booting. Once started, there you can connect the DualMiner USB! If they are already plugged in at startup, they will not be recognized!
Positive and negative
- No need for driver
- Sufficient energy for a majority of uses
- LED leaks light
- Assembly to be improved
To connect hard drives, USB keys or even DualMiner USB , the P10-U3 hub Orico is highly recommended. I had difficulty with the device insertion at the beginning, but if you opt for the metal version (product number A3H10) you will not have these problems as the case offers wider access. On the other hand, the metal version is more expensive.
If Orico could improve the assembly and ensure that each LED does not illuminate nearby LEDs, it would be much more enjoyable to use. For more intense use, such as multiple iPad charging, Orico could also increase the number of amps available.
