Usb Power Problem

[ro2124]

Recently bought a USB memory stick which connected ok.
But then loads of problem keeps cutting out every few minutes and restarting.
Well I am using it on a USB hub and noticed before there are always problems unless a device is directly connected to the computer.
Seems unless directly connected there just isn't enough power for other devices. Usual crap with windows I suppose.
Actually aforementioned hub is a powered hub with mains adaptor but even that doesn't seem to work properly.
And I did try the memory stick directly on the computer USB and it seems the problem did not exist then. so it's obviously a power issue.
The Hub I bought was from Amazon

Can anyone recommend a powered hub which does the job better?

Actually they do sell a 12 volt 3 W model, which appears more powerful, but I always thought USB is 5 volts so perhaps someone can enlighten me on that.

Well,12 volt is more than double the usual 5 ,so want to be sure I don't damage anything

In simple terms the power supply that plugs into the mains supplies 12 Volts at a couple of Amps to the hub. The hub then converts that internally to 5 Volts and a lot more Amps.

Ahh ok thanks, best go for 12V and more amps then
