USB hub not working? Powered Vs Unpowered

Today I discuss briefly USB hubs - Powered or Unpowered, what's the difference?

If you liked the video it would be EPIC if you could hit the like button... Can we get 10 likes?!

YES, you've helped me to understand WHY all of my USB sticks don't work at the same time, when I have 'em connected to my USB hub! I thought my hub was broken but you've explained what really goin' on with it. THANKS!

Very useful information. I'm sure we're all here for the same reason, but I think my problem lies more with the hub itself... It completely (well, almost) bricks my PC while plugged in, mainly during boot up, sleep, restart, shut down.. as soon as I unplug it, it goes right back to normal. It's the weirdest thing. I am new to USB-c ports on a PC (that's all that mine offers) and all of my wireless accessories (not over Bluetooth) require the typical USB 2.x/3x so I have to have a hub. I'm not sure how a USB c out struggles with a mouse and/or keyboard transceiver 😒
Getting a new hub later today and I guess I will update about how it goes compared to the one I most recent got (I hope it helps someone out there scrolling around). Anyways, I'll post an update tomorrow or the next day if all goes well with the package in transit lol.

If your going to use a dc jack please make sure you don’t get one that is over the limit of voltage I ruined two items.

Never found a USB hub that would work at all using usb 3.0 the same hub would work almost all usb 2.0 devices

WHAT ARE THE SPECIFICATIONS FOR THE POWER ADAPTOR THAT ONE CAN USE WITH THESE 4 PORT HUBS?

[MrFunnyMint]

Thanks, I was wondering what was this extra port in my hub

[KirubelTamene]

Just plug in the 5v power suply to it, That's what this video is all about!

[fdleothelionkid]

I have the a 4 ports one and I use it for my mouse and keyboard on ps4 for when I'm playing games such as minecraft
The lights on the devices will turn on but they keep disconnecting and reconnecting or just not responding when the lights are still on

All USB Hubs i had tested had a really big problem with power, also if Hub has extra power from wall.
1.- Connect a USB HDD mechanical and wait till it is accesible
2.- Connect another USB HDD mechanical and all previous USB HDD connected loose power during an instant.
That makes USB Hubs unusable for USB HDD (mechanical), since they loose power while another one is connected.
Imagine that happening while hot replacing a failed HDD on a USB RAID configuration, all disks loose power and all disk on the RAID are marked as BAD.
If not RAID it is also a problem, transfers in progress get interrupted.
And also Worst, with some USB SSD (and also some USB NVMe) they get damaged in such way that they get not be reconogized again (permane t damaged) because sudden power loose.
I can not find any review/test about this and i am getting mad to find a USB 3.x HUB with at least 4 ports (better if each port has its own switch to put that port ON/OFF).
Any help is wellcome.
Note: USB A type connectors and better if 10gbps.

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?

thanks for the info. i was wondering why i was getting so many usb not recognized errors and this solved it for me

[Obmuj]

Brilliant. New USBC adapter hub and one USB3 port on the hub (used for my File History backup) just stops after a while. I unplugged iPhone USB charger plug (also in the hub on another port) and of course (derr me) it was probably trying to draw power to charge (even though no phone was actually attached, btw) but as soon as I took that connection out the one with problems (File History USB stick backup to remind you) popped back to life. So point is: that bit of info on power and usage of several items was the answer so, as I say, brilliant for a well explained solution to problem. Thank you.

[FairwayJack]

good stuff ... can you advise the required output on an adapter for 4 port USB hub ?

[cds]

What power supply do I need for the first usb hub.?

[ronloveflying]

Thanks for the video. One question. Can you leave the power supply on all the time or I'll have to switch it off every every time I shutdown the computer?

[VOLTRONDEFENDER]

I do have hdmi switch that came with usb cable for power and it fit perfectly on my usb hub

[emmausroad]

Great advice, explains the problem I had using mine with a 2TB external hard drive, thanks

I hadn't considered bandwidth being affected.
