Hi, My name is Paul and I have jkust purchased an Acer Aspire XC-105 which I have installed windows 7 64bit on. However the USB 3.0 Host Bus doesn't appear tio be recognised. with the AMD Chipset drivers that Acer supplies.
I have tried the Win 8 and Win 8.1 drivers to no avail (Chipset_AMD_22.214.171.124_W8x64_A and Chipset_AMD_126.96.36.199_W81x64_A) respectively.
I have also tried to look for the AMD driver for the device via the device Hardware ID (
PCI\VEN_1022&DEV_7814&SUBSYS_08001025&REV_01) again to no avail. I believe this to be an AMD A45 chipset but cannot lcate it on AMD's site.
Is any kind soul willing to give me a pointer as to where I might locate the driver for the units front USB devices..
Many Thanks in advance

It's okay I have fixed it... It DOES NOT install from the supplied Acer Software (Catalyst supplied by AMD) at all !!! It doesn't even see the device in the device list in Catalyst... I found it in some HP drivers and installed it from there. Being an ex application packager helped me here... but other people may strugle with this one..

Hopefully this will help people trying to get the USB3.0 driver working under windows 7 for these XC 105's.
From the acer.co.uk support site search for the Windows 8 drivers for the XC-105 and download the chipset driver.
|Chipset||AMD||Chipset Driver||188.8.131.52||208.6 MB||2013/06/10|
Right click the .zip file and "extract all" to a folder of your choice.
Browse to the following directory for windows 7 32bit:
OR browse to the following for Windows 7 64bit:
(If you are unsure of your windows version click START > Right click COMPUTER and check your version under the system information)
Now you need to edit the amdhub30.inf (driver) file which is listed as type "setup information".
Right click the file and choose "open with" and then select "notepad". You may have to expand "other programs" to find the option.
You will need to edit the file and replace all instances of "5.1.1" with "5.1". The easiest way to do this is to click "edit" from the taskbar and choose the "replace" option.
Complete the following:
Find what: 5.1.1
Replace with: 5.1
Click "Replace All" , close the box and then save the file and exit it.
Right click the amdhub30.inf file and choose the option to "install". Choose to install the driver if you are prompted with a red warning box.
Now repeat the above process for the amdxhc.inf file found in :
(selecting the file again based on your windows version)
Once you have successfully installed both driver files go into the Device Manager (START > Right click COMPUTER > Select "Device Manager")
The USB controller should currently be sitting under "other devices". Right click this and uninstall it.
Then from the taskbar in the Device Manager click the button for "Scan for hardware changes".
This should then go through the process of adding the USB 3.0 controller correctly.
Works for me!

If this doesn't work for you please try running the .msi windows installer file from each folder and following the process through. ( amdhub30.msi and amdxhc.msi)
Or another solution would be to replace "5.1.1" in the .inf files with "6.1"

I just purchased the XC-105 and it came with windows 8 installed , but I am finding that the 3.0 usb ports are not working. I do not see in the device listing a 3.0 root hub. Would all thos above steps also be for the problem I am experiencing?
Please any help would be appreciated. Aslo nice work Paul
