AO722 problems with USB Hubs

crisorlandobr — Mon, 10 Mar 2014 19:53:43 GMT

Hello there

I am using this netbook as my main machine for some months since my other notebook does not work anymore

And sometimes USB powered hubs stop working from nothing

I have 2 USB hubs attached to the machine
Main Hub, its an USB 3.0 model that works with USB 2.0)
3 externally powered HDDs (all 3,5' HDDs with external power)
1 slim DVDRW
1 audio control unit (not MIDI, but guitar recording)
1 external wireless dongle (internal wifi has poor signal)

and sometimes I use my backup external HDD with it

The other hub:
Mouse

External keyboard
Cooler(fan)base
Wacom tablet (bamboo model)
And 2 spare ports to use with pendrive

I know there is a lot of things connected to a netbook, but since the main "power eating" devices (external 3.5' HDDs) are connected to external supplies, why the USB stops working out of nothing ?

Is this something BIOS related or can be a faulty mobo ?

Here I use Windows 8.1 and I have been with this issues since Windows 8, since when I had Windows 7 installed I did not use this machine with the hubs.

Any ideas about what I can do ?

Tks !

You are doing very well on that 722, my friend. Have you upgraded to 4 or 8GB ram yet? If not, that's my first suggestion. If you have, I suggest ercovering Win7 if you haven't deleted the recovery partition yet.

Actually I could manage to make this work here

I changed power management settings to USB devices inside W 8.1 with some regedit tweaks

But I hope those workarounds realy keep working

And yes, I upgrade the device to 8GB the same week I bought the netbook

And I do not have the W7 partition since I chnaged the HDD to a 750GB hybrid

Tks
