I have an Acer V5-551 notebook with Win7 on it. I cannot find the drivers for the SM Bus controller and USB controller. The Acer site has proven to be useless for this. After you upgrade your computer to Windows 10, if your Acer USB Drivers are not working, you can fix the problem by updating the drivers. It is possible that your USB driver is not compatible with the newer version of Windows. USB devices not being read on my Acer V5-573G laptop hi there, I have a brand new Acer V5-573G laptop.

Morning all, occasional lurker, first time poster.

I own an Acer Aspire V5-122p - technical info here. It's basic but does the job, or did do for a while.

Standard Enhanced PCI to USB Host Controller. Download driver. ELAN SMBus Driver. Download driver. AMD MMC/eMMC Host Controller - 0300. Download drivers for chipset for Acer Aspire V5-122P laptop for Windows 7, XP, 10, 8, and 8.1, or download DriverPack Solution software for driver update. Popular Drivers. Acer Aspire V5-121 chipsets Acer.

Decided to try and downgrade my laptop, which was originally shipped with Windows 8.0, to Windows 7 (64 Bit) as a result of the botched forced rollout of Windows 10, which caused it to run so sluggishly it was basically unusable, even with the usual speed-boosting techniques applied.

Long story short, after much battling with stubborn drivers, and a lot of switching my memory stick to and fro between its one functioning USB 2.0 drive and my desktop unit, I've managed to install pretty much every driver I need except one - the USB 3.0 port on the left hand side.

Now according to pretty much every website I've scoured, the correct driver is the AMD USB 3.0 eXtensible Host Controller (0100 (Microsoft) Standard SATA AHCI Controller). However, whenever I try to install what is claimed to be the 'driver' for my port, all it does is try to install a new copy of the AMD Vision Engine Control Centre (Catalyst). Nowhere have I actually been able to find a driver for the USB port itself that doesn't come bundled in with Catalyst, and I'm struggling to work out how this program has anything to do with installing the necessary driver. A screenshot of the program itself is available here.

I have been able to pinpoint the correct driver in the download folder, but every time I try to install it gets stuck in a loop of asking to redownload the catalyst installer (see this screenshot).

Worth noting that AMD UMBus is having trouble installing - though I don't understand why that's causing the install loop.

I know the port itself works, as I can charge devices from it and my mouse, if plugged in, draws power but simply isn't recognised by the PC. I am also aware that as a machine that shipped with Windows 8, there are parts of my V5-122p which weren't designed for Windows 7. I don't buy the argument that it will never work, as some more doom-mongering respondents on other similar issues have suggested - after all, I had a lot of trouble getting WLAN to work, and yet I'm able to post here now!

Any help would be appreciated, and I will get back to you if anything changes. Many thanks!
