I have the Acer p243-m which came with win7 ... After installing windows 8 , I saw that the usb 3.0 drivers were not working at full speed .. If previously I got a speed of 100 mbps from my pendrive now it gives only 28 mbps ... So , what do I do .. Do I update my bios ??? If so , please direct me , I mean the exact links and which file to download and use coz bios updating is risky AFAIK ...

Yep, risky. You prolly won't like my advice. But I suggest you upgrade back to Win7 if your recovery partition is still intact.

Bro , isn't there any other solution ??? Please try and think of anything ... Coz after using Win 8 , Win 7 seems a bit old ... Besides I have many softwares installed ... You can take a bit of your time but please try and think of any other solution ...

Did you use acer or generic upgrade disks?

I might suggest updating your chipset drivers from our website.

Are you using the same device for testing the speeds? There are some power requirements and I believe that can affect speeds with USB 3.0

[Joker]

No , I am not using any upgrade disks .. I downloaded the ISO and then installed it clean ... And I am using the same device as I did on Windows 7 ...

[JackE]

Try Acer-Cory's suggestion and update the drivers.

Nope that didn't workout either ...

This may be related to your USB3 issue. http://www.intel.com/support/chipsets/usb3/sb/CS-033870.htm Apparently Intel didn't do a specific Win8 controller due to MS designing a native Win8 controller. So Intel recommends uninstalling the Win7 host controller *before* trying to install Win8.  Since you used a clean iso install, you may not have gotten an incompatiblity warning and the Win7 controller is still there. Perhaps you can go to Device Mgr or Uninstall to check what controller driver is actually on your system.

Guys , I uninstalled all the usb drivers including root hubs and then restarted the PC .. Then I did a scan for hardware changes and the drivers reinstalled ... Then another day , I plugged in my friend's usb 3.0 hdd and it read at max 30MBps ...

So , I unplugged the device and restarted my PC and then tried copying and it gave 130MBps at start and then dropped to 80MBps on an average .. Now , the problem is that I can't always restart the machine just to use the usb 3.0 drive ... So , what do you guys recommend now ????
