I'm not sure I can clarify my question to one single concise sentence. Please see the paragraph below in bold.
I can't figure something out and when I asked myself where I had the best collection of tech savvy nerds that scare me with how smart they are TBT immediately came to mind!
Help me Brothers!
I have an FZ-G1 that I use for my everyday computer. I have it plugged into a FZ-VEBG11U desktop dock. I also have an Orico A3H10 10 port powered USB HUB http://www.amazon.com/Super-Speed-Switch-Aluminum-ORICO/dp/B00CN40X12/ref=cm_cr_pr_product_top?ie=UTF8
When I dock my tablet it is telling me I don't have enough USB Controller hosts. A quick google shows pretty compelling evidence that the issue is the amount of power available to my USB hub.
The dock I have is powered as well as the USB hub (everything is powered).
My ultimate question is power related. When I bought the 10 port HUB I specifically bought it because it was supposed to be a higher powered device with 4A of power. I look at the power adapter and it specifies
3000mAFirst off, if it has 1A input how does it output 3000mA? Isn't 3000mA 3A's? I know more about electricity than most people but far less than most electrically educated people. My understanding of Ohm's law would tell me that if I were to change the Voltage and resistance I could change the amperage. I see the output Volts is 12 from 100-240V and I'd have to assume the unit has step down converters to achieve this, thus changing the Ohm's (not particularly mentioned anywhere). Does this work out correctly?
The 2nd part of the question has to do with the power distribution. My common sense tells me that if I have a 10 port hub with 4A's of power (allegedly) it would distribute the power to the ports that ask for the most or evenly distribute it.
There are also 4 port USB 3.0 Hubs with the same 4A of power. Wouldn't the additional 6 ports be "weaker" if the power is the same? I cannot seem to find a 7-10 port USB 3.0 HUB that advertises more than 4A's. Is there a limitation I don't know about?
