8890 USB2 Problem Under Vista

Thread Starter 
I have a Sager 8890 that works beautifully under Vista, except for the fact that it thinks its 4 USB ports are all USB 1.1, not 2.0. In device manager, it shows that I have a USB2 Enhanced controller. However, when I plug in USB2 devices, it always tells me that my devices could perform faster if I plugged them into USB2 ports instead. I only have the four ports next to the A/C adapter plug.

Help! Thanks.

Rob

From the specs for the 8890 I can verify that the four USB ports should all be USB 2.0. So it's most likely going to be a driver issue. Vista has built-in support for USB 2.0, so it should really be installing the right drivers for them itself. The first and simplest thing to try is removing every single item listed under Universal Serial Bus controllers, then reboot and let Windows redetect them all. I have seen that resolve quite a few problems like this.

If that doesn't work, consider reinstalling your chipset drivers. Normally, you should have installed those first thing after the Vista setup finished. If you didn't install the chipset it could be causing this.

If that is the case then my brand new quad system's USB ports are also 1.1, which they are not. They indicate exactly what yours do, as does my 8890 also. I don't get that message when I plug in USB2 devices. Try timing them to see if they exceed 11mbps. thats about 1.xMBps. I just transferred some things to and from a 4Gig USB card and got around 7.7 or so MBps which is way faster than USB1. I DL'd some photos from an SDHC card and it was about the same as well. I think something else is going on.

Hi Digg,
My system shows the same usb devices as yours. When plugging in devices, my system incidentally gives the speed message. XP did that as well. I don't know why it does that. Maybe clearing out the ("hidden") devices once in a while helps?
