HP Pavillion a815n freezes when connecting a USB Hardrive or MP3player

vincentvintris — Sun, 11 Mar 2007 08:42:20 GMT

Our Desktop has an issue when connecting either a WD MyBook ext HD or a Sansa MP3 player to a USB2.0 port.
When doing that the MY COMPUTER screen freezes.(NOT RESPONDING, Hour Glass stuck)) The two devices can't be accessed.
Installation,recognition seems to be OK.
Happens for each of the two individually.
Freeze goes away when device is disconnected.
Other USB devices Scanner, Extigy Sound system, SD Disk Reader work fine.

No USB Hub used.

Sansa MP3 player worked fine for almost a year. Problem suddendly apeared. No reason/change that I can point to.
New ext HD now has the same issue

Have tried to uninstall USB devices in Device Manager. No result Have disbled USB Legacy support in BIOS. No result.

Driving me nuts. Help would be great. Thanks
VV

All you can do is update your drivers.

Also check the device manager to see if all is working prior to updating.

Hello Rich,
thanks for the advice.
I had looked at the driver updates before. However didn't see anything that would apply to our problem.

I updated my BIOS though.No result.

Can you point to specific drivers that I should update?
Thks

Vincent,

Just for whatever it's worth, take a look at this thread. Not recommending it, but it seems like the settings could be experimented with with no risk (just set them back to where they were before):

Try updating your Intel 915G drivers.

That should cover the USB too.

...these driver updates are pretty straight forward.

They will inform you if you do not have the correct hardware etc prior to actually loading.

My WAN at work is almost 1000 PC's and the biggest problem I face is USB devices like thumbdrives. I have actually seen thumbdrives knock out device drivers for other USB devices just by plugging them in but removing them without "removing them safley". This is of course USB 1.1 that does this. You are supposed to be able to "hot swap" or unplug a USB thumbdrive without having to "safely remove the hardware" first.

The good news is reloading the USB driver fixes the problem that the USB devices cause.

Here are a couple of great articles on USB...

Let us know how it works out for you.....

I never asked but do you use USB 1.1 or 2.0?

just curious...
