The Most Efficient Way to Update Sony Drivers

There are a number of frequent alerts and also other messages which you may get in the driver upgrading process, many of which I've paraphrased and listed right here along with information on what to do:

QUESTION: So I have a Sony Vaio SVD11215CYB and the usb ports are not working. Optical 3 button mouses cannot connect nor can my USB both of which work on other computers. I have absolutely no idea what the problem is.

Although, I looked into device manager and found USB root hub xhcl had an exclamation mark next to it. It says that it cannot load the device driver for this hardware. The driver could possibly be corrupted or missing. (Code 39). Once I try to update the driver for it it says the driver is up to date. Does this have anything to do with it?

I've also tried uninstalling all the usb extensions and rebooting. It did nothing (All the extensions came back even xhcl with the exclamation mark).

I really have no idea what to do and any help will be appreciated.

ANSWER: Possibly the driver is corrupted or the USB devices are busted. Let's isolate the issue. Kindly follow these steps:

  • Power cycle - Remove the battery and all peripherals -> press and hold the power button for 5 seconds OR, if the battery is not removable, remove all peripherals -> look for a battery off button on the bottom of the laptop -> push the button for 5 seconds
  • Reset BIOS
  • Download the drivers for your Sony device.
  • Run Vaio update and Windows update.

How to Update Drivers with Device Manager?

1. Find Control Panel.

Note: If you don't see these options, your Control Panel view may be set to Large icons, Small icons, or Classic View, depending on your version of Windows. If so, find and choose Device Manager from the big collection of icons you see and then skip to Step 3 below.

2. Open Device Manager

From the open Control Panel window, click System, choose the Hardware tab, and then click the Device Manager button.

3. In Device Manager, you can check for updates, update your drivers or troubleshoot driver problems
