USB 2.0 Drivers? PCG-GRT916V

[mazeman43]

Hi there

I am hoping that someone out there in cyberspace will be able to help.

For some time now I have been living with getting told that the device I have just plugged in will work faster when plugged into a Hi-Speed USB 2.0 port. My laptop is supposed to have 3 Hi-Speed USB 2.0 ports. It all started when I reloaded the software onto the machine. As I am aware when ever reloading recovery software from scratch supplied with the pc, it puts the machine back to the state in which you bought it? This appears not to be so in my case.

Please help .

Hi Markzee and welcome to the Club.

I presume you have reinstalled all the Microsoft and Vaio Updates since your Vaio was bought?

Go to Device Manager and expand 'Universal Serial Bus Controllers'
Does it show a 'Intel USB2 Enhanced Host Controller'?
If yes, double-click on this, you can select the 'Drivers' tab and look at the driver details.
What drivers are installed?
The drivers are just part of XP_Sp2

Hi There,

Thanks for your time. Yes to your question re updates, as far as I know I have them all. With regards to your other question I have had a look and no. The controller is a SiS 7001 PCI to USB Open Host Controller and the driver details are 5.1.2600.2180 (xpsp_sp2_rtm.040803-2158), if this means anything to you?

All help appreciatted.

Hi MZ,

That probably explains why you have a problem - if you dont have an "ENHANCED" controller listed, you do not have any working USB 2.0 ports. Perhaps when you reinstalled an update, driver or some fix got missed somewhere along the line. You may have to reinstall XP_Sp2 with the correct drivers to get it to work.

Have a look at this web page to see of you can find any fixes: -

Also have a look at this thread from the 'Everything USB' Forum: -

Hi All, Me again. After properly checking 😞 I see I do have an "Enhanced" controller listed. Anyway I went the way of other advise if I cant get it sorted out and that was to buy a PCMCIA USB 2.0 card. But believe it or not, this wont work either. It is also coming up as a slow speed USB port. I have attached (I think) a jpg of the list of USB ports on my machine for assistance). The NEC USB is for the PCMCIA card and the Sis is the onboard USB ports. Anymore ideas, anyone, please?

Probably this is not the case but anyway. If you are using USB hub to connect more devices than what your laptop offers, you might have an old USB device (old mouse, web camera or something else) connected on that hub that forces all of the devices on this hub to be USB 1.0.

This might be irrelevant. I have the same SIS 7001 chip on my GRT815M and I have enough problems under windows (slow writing speed) but is still not that bad as USB1 . Under Linux everything is just fine. Try with a LiveCD to check that it is not a hardware problem.
