USB 2.0 Suddenly USB 1.1 in Vista

I recently was minding my own business, when all my USB 2.0 ports on My HP Vista system became 1.1!

Everything was working fine, then boom. Now it's a snail. It says all the latest drivers are up to date in device manager, I went to Intel and got the latest Chipset drivers, and I even wiped for a Vista reinstall.

I've taken everything off the hub and plugged in directly to the mobo USB, I even added a USB PCI card. No luck!

Everything always comes up 1.1 now. Driving me crazy! Any help would be appreciated.

Running a stock HP m7760n with Vista 32.
USB issues are with my external Hard drives, tried two, and my external writer. Tried them on other computer, no issues.

I have a HP Pavillion m8100y w/ vista 32 sp2. I've been trying to fix this same problem for months now. Hp has been no help. I've tried just about everything. USB 1.1 is cramping my style. Help!?

Kind of a longshot - but have you checked your BIOS settings?

Bios settings

The USB legacy support is disabled in bios.

That setting is okay. I was thinking you might have a setting like I have in my AwardBIOS for Onchip USB - possible settings are V.1.1, V1.1+2.0 or Disabled. Sniffing around though, I did stumble on this article at the HP site that concerns a Microsoft fix:
Another longshot though, since you probably already have those updates. Strange problem - I'd like to know what's causing it too.

In reply to: re: USB legacy support

I appreciate the input, and will let you know about some of the things I've done in trying to fix this issue. Most of this is based on other forums.
1. Updated Chipset Drivers through Intel, Updated with older drivers also just in case.
2. Ran all windows updates.
3. Ran all HP recommended Hotfixes. They all said that my machine didn't meet requirements and would not install, presumably because updates were...... up to date.
4. Updated BIOS, reset BIOS.
5. Device Manager Update Drivers(said drivers were up to date)
6. Updated every driver on the hp website for this rig.
7. plugged all USB devices in directly to rig(no hub)
8. Turned Legacy Off, then on tried in both scenarios.

9. This finally kind of worked, but not a fix:
Uninstalled all USB Root Hubs in Device Manager, and restarted.
Plugged in a USB Key and held breath. 2.0! Plugged in old External HD, 1.1!

Repeateded process of uninstalled USB root hubs, restarted, plugged in newer external HD, and 2.0! Plugged in iPhone, and 1.1.
The best I've been able to do so far.....

device manager

In reply to: "I have detailed Files" - Terminator 2

In the device manager under USB controllers there are
6 "Intel(R)ICH9 Family USB Universal Host Controller-2934" and
2 "Intel(R)ICH9 Family USB Enhanced Host Controller-293A"

I only have 6 USB ports (two in the front and 4 in the back).

tried that

In reply to: re: USB legacy support

Been to that HP page a number of times. Tried the windows update and it said it did not apply to my system. Thanks for your help. Any other suggestions?
