Can someone that link me a USB hub that has omnidirectional output USBS. Specifically my problem is my powered USB 2.0 USB hub with 7 Sports doesn’t let my flash drive and phone with USB on the go communicate when they’re both plugged into the output ports.

Eleanor Fong says:

Hi Josh, thanks for the video. It cleared some of my doubts. I would like to ask a question. Is the power from the powered usb hub dependent on the power output of the computer’s usb port. I am using a usb device on a tablet pc (microsoft surface 3) and apparently it affects the performance of the usb device compared to when I use the device on my laptop. I was told by the manufacturer of the device that it is due to the limitation of the power output from the tablet pc. Thus i was thinking of using a powered usb hub to resolved this issue but I am not sure whether the power output from the usb hub is in part determined by the tablet’s usb power output. My guess is it is not but i would like to seek advice from experts like you. Thanks a lot.

very educative info Josh … I have been tearing my hair apart since dogs ages as to why my peripherals wont work with usb hubs… however, i still have a doubt.. since the usb port recognises a device in that specific port, then how does it differentiate between all devices when connected via a USB hub?
i am an avid gamer and use sim racing equipment which needs to be connected via usb. for example if i connect my racing wheel, gear shifter, other various peripherals, headphones / mouse etc, via a usb hub, will it all be recognised separately as separate devices (given that its a powered hub and drawing enough power) ???
your inputs will b of great help ..
thanks !

Can you tell me if this HUB would be a good option? It has a power adapter already…

Andrew Crump says:

Can I plug this in a power bank to give it power??

DanteAxe_SW says:

Elizabeth Sanchez says:

Im guessing you can’t charge your phone with Ports?

Stijn van der Wulp says:

Thx for the vid, really helped me out!XD

Zoom 111 says:

Great vid but I’m still confused as to what one to buy so if you buy a powered one it won’t work because of the band width so what one should I buy is the question. I have just bought an iMac 2017 help

Miro555 says:

it’s hard to figure out an english pronouciation(((

Kieran McGeehan says:

i have the 7 port version of the hub you have in the video, my problem was that i had 6 devices on it (mouse, keyboard, mic, webcam, usb sound card and my phone cable) all of my peripherals were lighting up but then, they all seem to have cut out, but the lights were still on. once i switched them off and switched them back on again, it still wasnt working. (i didnt try plugging an extra power supply in yet cuz im lazy and i dont wanna run up to my attic rn)

Ed Straker says:

Thanks mate. I learned something!

artsandlife says:

Guys… What happens when sudden power outage occurs? And you have and External Harddrive connected to self-powered hub… Will the External HDD be damaged?

eazyrat says:

jesus that background music is annoying. turned the video off.

Mark Hamilton says:

I have nearly the same device as that what is the power supply called to connect up to it?

iJamie8467x says:

I should buy this. I recently bought a Oculus Rift and that used almost all my ports 🙁

uksuperrascal says:

Hi Tech ? – you keep calling it power ? power relates to volts and current, you are very poorly explaining, it is not a lack of power, it is a lack of one component of power, the current, ie, current is the amount of energy flowing in a circuit, not the voltage. In a circuit if you try to draw a higher current than the supply Current can deliver, then the voltage will fall as well when overconsumption occurs. So for the 4 input usb hub = 4 * 500 m.a = 2000 – I recommend a 5 Volt 2.5 Amp P.S.U. – I score your video 4 out of 10 : I will not click a thumbs up or down or subscribe 🙁
