Hi all.
I am on a Compaq laptop, and the other day I upgraded myself to Vista Ultimate. I just got home today and plugged in my usb hub and have been running into some strange problems. Everything will work fine, and after a little bit on the computer all the usb ports will stop working. I have plugged many devices into all of the ports and it's like nothing is even happening. I checked everything in the device manager and it says everything is working properly. Not sure what the problem can be. Once I restart the computer, all is good again. Any ideas?

Thanks,
John

If the hub is a USB 1 type it will not work with Vista, you need a USB 2 type.

Any USB 1 device will run a lot slower on Vista.

After you "upgraded" to Vista, did you immediately visit the HP site to get all the required Vista drivers for the laptop (assuming there are some?)

The native Vista drivers are not universal in compatibility, similar to any Windows version, the maker specific drivers are often needed.

I have installed all updates from both windows and HP. This problem (along with other little ones), are still happening.

The only new insight I have is:
After the usb ports stop responding, I will shut down the computer and it will give me an error saying that Explorer is still running and trying to play the log off sound. I have to then terminate Explorer and shut down. Note: My sound card and speakers are both through my usb. When the usb ports quit, so does the sound / sound card.

I have not been able to figure out what triggers the usb ports to quit. Everything will work fine for hours, then out of nowhere, everything plugged into the usb stops working.

I'm wondering if maybe my machine just isn't agreeing with vista?
