Z820
Microsoft Windows 10 (64-bit)

I ran into a problem with my new(refurbished) Z820. I'm using a wireless Logictech mouse, but whenever I plug any kind of storage device into any USB port, the mouse stops working. I've tried moving the receiver to all the other USB ports, but get the same malfunction.  A corded USB mouse works just fine... The only way I've managed to get the receiver to work is to plug it into a hub. I know this makes it a non-issue, but I've never had this problem with any other computer.

 

Any ideas?

 

Thanks;

Rob Pleak

Rob Pleak,

 

I can only think that the storage device and the wireless mouse receiver drivers are setting up some kind of conflict, or it's a problem with the USB controller driver.

 

Only a few days ago, we had a related situation. Three of the four office HP's- two z420's and the z620 suddenly had the same problem in that USB 2.0 devices- flash drives and external disks would not be recognized in the USB 3.0 sockets- as they have been,  but would run on a USB 2.0 hub. The USB 3.0 flash drives would not run in the 2.0 either, but the 3.0 external drive would. - Crazy. 

 

The solution turned out to be a simple reinstall of the USB controller driver.  This is a link to the one for the z820:

> and that seems to be the same version as for the z620  and z420 as well. - Worth a try.

 

That driver is dated 2014- so it's not an update, but for some reason, all the systems using the same controller simultaneously had this same problem and the reinstalled USB controller driver solved it.  Possibly, some Windows update simultaneously affected that driver.
