So I recently purchased this thing ...

 

https://www.ebay.com/itm/Black-USB-2-0-Hi-Speed-4-Port-Splitter-Hub-For-PC-Notebook/301586172040?epid=1939398653&hash=item4637efc888%3Ag%3A9xgAAOSw%7ERVaH2fv&_sacat=0&_nkw=Black+USB+2.0+Hi-Speed+4-Port+Splitter+Hub+For+PC+Notebook&_from=R40&rt=nc&_trksid=m570.l1313

 

... and almost immediately, I started having problems with it. Devices I had plugged into the thing would either not work at all (sometimes they would work if I plugged them into another USB socket on this hub, but I shouldn't have to do that), or would randomly stop working like they had been disconnected.

 

Then after about a week, the whole damn thing stopped working altogether. Literally, just the first week!

 

is there a USB hub out there that I can trust to work consistently for at least a year after purchase?


My current build:

 

Motherboard: Gigabyte GA-970A-UD3P
Processor: AMD FX-8350
RAM: 12GB (2x2GB+8GB)
Video Card: Geforce GTX 1050ti

OS: Windows 7 64-bit Ultimate

I have two of these, one at home, one at work.  They are powered USB3 hubs and the newest is over a year old.

There are hundreds of USB hubs on the market, most are cheap and rather flimsy.  I paid $25 USD for a 4 port hub and external power supply.  I use it mainly to power external things like fans for the laptop and charging devices.  I never use the USB ports on my PC or laptop for charging anything, only to interface other devices and those devices have their own power sources.

And lurking in the background are the requirements for USB devices.  The device is supposed to get .1 (point-one) amps of 5 volt power so it can identify itself to the host and then the host for USB 2.0 is allowed to provide up to a total of 1 amp (5 watts).  With an unpowered hub, those numbers are for ALL of the devices added together so a keyboard, a mouse, and a flash drive; you're toast (much less use a portable hard drive!).

Things that have there own power supply don't need to be counted; but even a mouse and a keyboard will need a powered USB hub to work.

Most machines I have had to service because the user overloaded the USB.  I can't find any that will support more than 500 milliamps (1/2 amp) and it's easy to overload them and difficult to repair, some even vaporize traces off the MOBO.  Some repeat users get traces cut and terminals mounted to install pico fuses to prevent further damage and ease of repair.
