Disable xHCI on Flip 13A

I recently purchased a flip 3a and was planning to use it with a tuning program for diesel trucks. I ran into an issue with it not being able to connect with the vehicles ecu, according to experts with that program it has been remedied by disabling xhci to restore the usb port to 2.0 but I can't find where to disable this feature. I have gone into bios via the "assist" button and cannot find it. I don't know if this is harmful for the laptop but I would like to at least disable it long enough to test the program. Thanks Butch.

 

Can you try using an old USB 2.0 hub? If that works, it might be the easiest way. Otherwise I'm thinking you'll need to force-install an old driver for the USB controller, which is likely to mess up other devices that use USB.

 

From my understanding it has more to do with the interface than it being a 3.0 vs. 2.0 port. It seems like any other brand you can turn it off in BIOS but I'm not seeing it for my VAIO.

 

Bump, anybody else?

 

Can you try running the program in a virtual machine? That often has older, less capable simulated hardware.

 

I'm not sure what that is. I've used the program several times on my older dell with windows 7, the recommended fix from the software developers is to disable the xHCI and several users have done this to alleviate this issue with no problems but I can't find where to do it on this unit.

 

VAIO stock BIOS sucks - too many of the avanced features are hidden. Many people have modded the BIOS for several older models, which exposed many more features and settings. I don't know if anyone has modded the BIOS for the newer models, though. If the feature you want isn't in the stock BIOS, there is very little you can do about it.

If you are running Windows Professional or better (the home premium ones don't have this, so don't even bother), you can enable the Hyper-V feature.

To enable Hyper‑V on Windows 8.1 (same method for Vista and above)

In Control Panel, tap or click Programs, and then tap or click Programs and Features.

Tap or click Turn Windows Features on or off.

Select Hyper‑V, tap or click OK, and then tap or click Close.

Shut down your PC, and then restart it.

Depending on your manufacturer, you might have to pause a few seconds with the PC off before restarting for the required changes to take effect. If you're using a laptop, you might have to remove the battery before restarting.

Now create a new virtual machine and configure it. Install Windows on it. Now try running your program in that.

If there is an entry for enabling virtualization in your BIOS, enabling that will certainly improve the performance of the virtual machine.

If you don't have a Pro or better version of Windows, try VMWare.

 

Ok thanks that told me what I needed to know. I'll just use my older windows 7 dell for tuning and leave this one alone when it comes to that.
