Solved Sony Vaio PCV-RS246 - USB 2.0 working as 1.1

July 18, 2012 at 07:26:52
Specs: Windows XP Professional, IntelĀ® PentiumĀ® 4 processor
Hi Guys,

I've been going crazy over this, I've been googling for days but I can't find an answer.

I have an old Vaio desktop (PCV-RS246) running on Windows XP Professional, everything is working fine apart from my USB ports.

Whenever I plug something in it says "this device can perform faster" but this computer is definitely usb 2.0 not 1.1, so I'm confused as to why it's not working properly.

I've already tried uninstalling all the USB drivers in Device Manager, and upon reboot the "enhanced USB" did not reinstall.

Can anyone help me out please?


Here's a screenshot of my Device Manager:

Watch the screen carefully when you cold boot. It will tell you what key to press to enter Setup. Could be Delete, don't know. When you get into the Setup (bios) look for your usb port configuration. See what it's set on, if necessary, change it to usb 2.0. Save the changes you made and exit. If that''s what it was, that should fix the problem.

You need at least Windows XP Service Pack 1 for USB 2.0 support.
You can get Service Pack 1, 2, or 3 from Microsoft Update website or enable "Automatic Updates" and they will be downloaded & installed automatically.

Service Pack 1 must be installed first, then you can install Service Pack 3 (no need to install Service Pack 2 because Service Pack 3 includes all the updates from Service Pack 2).

Thanks for your reply, I've already got all of the service packs, I'm currently on SP3

Are you running WinXP SP3?

Are the devices you are connecting high speed devices?

Are you connecting directly to USB ports or to hubs? Card readers are one type of hub.

Yes I'm currently running WinXP SP3 Professional.

The devices are high speed usb flash drives for example, and usb 2.0 external hard drives.

Yes I'm connecting directly to USB ports, I'm not using hubs.

""enhanced USB" did not reinstall." This is the issue.

Either you need to go to the Sony site or the chip's OEM site for the correct driver. If not, you may need to recover the system from OEM media.

Did the USB ports ever work as USB 2.0?

How are you updating the USB drivers and where are you getting them from? Intel no longer supplies chipset drivers for your chipset so I assume WinXP sp3 has them included.

Do you see the message with all USB devices?

Are your external USB hard drives externally powered?

Post the USB driver version and date from the driver tab for the USB controllers in Device Manager.

Are you using a USB keyboard or PS/2?

If PS/2, I suggest you remove ALL USB controller entries from within Device manager and then reboot.

Yes they used to work fine as USB 2.0, I don't know why they're not working now.

As you said Intel no longer supplies chipset drivers for my chipset. (Let me give a bit of background info to see if it helps, this Vaio PCV-RS246 was originally XP Home Edition, but a couple of years ago I purchased XP Professional which included SP3. So I then did a clean install with that XP Pro CD and I then individually installed all the drivers that I downloaded from the Vaio Website. So I didn't use the original recovery disc that came with it because I just downloaded the drivers from the website.) I actually haven't updated the USB drivers because I do not know where to get them from, could you help me out please? I have tried updating them through device manager but it doesn't work.

I see the message with all USB devices that I plug in.

From the driver tab, the USB driver date is 15/01/2003 and driver version is 5.0.1006.0 for the "Intel(R) 82801EB USB Universal Host Controllers" but for the "USB Root Hubs" it is 01/07/2001 and driver version is 5.1.2600.55152.

My external hard drives are externally powered.

I'm using a ps/2 keyboard and a usb mouse. I've already tried uninstalling all usb controllers and rebooting, but "enhanced USB" never reinstalls, I just end up with the same thing.

Why do you say the driver never reinstalls?

Could it be that there is a bios setting to disallow usb 2.0?

I can't see the "enhanced usb" driver anyway, so it never reinstalls, only the 6 usb components reinstall (they are on the screenshot that I put in first post).

Not sure about my BIOS setting, how would I even check that?

Wow, you guys are amazing, thank you so much.

It actually worked, I entered BIOS setup with F2, but I couldnt find anything for USB configuration, instead I just chose "restore default settings".

When the computer turned on again, I plugged in my flash drive and the "enhanced controller" started installing.

Much appreciated for all the help!

Just for clarification, how/why was my BIOS preventing my USB 2.0 from working? I don't remember ever changing my BIOS settings...

Go back into the BIOS screens and see if the date in there is current. If it isn't, then your CMOS battery is failing and needs to be replaced. The CMOS battery is a silver coin shaped battery mounted on the motherboard. Be sure to pay attention to which side is up when changing it if necessary. Also unplug the computer prior to removing the battery.

You may need to enter the BIOS again on first start up to reset some values, like date, time, boot order, USB, etc.

Time and date are current, so CMOS battery is healthy. Cheers.

Forgot to mention that you need to interrupt the power to the computer and then check the date on the next restart. The date will hold when reset even without a battery installed as long a AC power is available.

I unplugged from AC and checked BIOS again, date and time are fine.

What do you think may have caused this USB problem in the BIOS originally?

Did anyone have access to the computer besides you? Kids do things all the time and sometimes don't own up to it.

I don't understand why the default setting for USB would be USB 1.1 anyway. Most BIOS files only mention USB when concerned with using USB devices in the POST screens. The setting is "enable legacy USB devices".

I am wondering if the BIOS settings were to have the hardware controlled by the BIOS instead of the OS (Windows). That might explain things.

That would be the ACPI settings. See the link below for further info on ACPI.
