I hope someone can give me some advice
I seem to be having an issue with my unifying receiver on my HP Compaq 6710b laptop.
It started out that while my mouse was working, all of a sudden I get a popup message that says "USB device not recognized" and then the mouse stops working.
The I could unplug the receiver and plug it back in and it would continue to work for a random amount of time.
Currently it is not working at all on my laptop. Just says: "USB device not recognized"
I have tested the receiver and mouse on another PC and it works fine. I have also tested a normal corded mouse on my laptop and that works fine too.
Even though I actually work in IT, I am stumped.
I've reinstalled the Chipset drivers, and tried a few other tweaks, but can't seem to get it to work.
At this point in time I am thinking to brick the laptop and get a new one, it might just be time

You just want an excuse to treat yourself.
Debugging USB issues can be a challenge, even for an IT specialist.
One thing to look for is stuff left over long after you removed the USB kit and pensioned it off.
If you go into Device Manager, get it to "Show Hidden Devices". (It is in View.) Then you'll see a bunch of "greyed out" devices. Might be worth clearing out anything that looks promising. You aren't likely to do much damage. Windows will reinstall any that you need when you next plug in the device. But create a Restore Point before doing anything drastic.
Similarly, check out other areas for unused kit. Human Interface Devices, Keyboards and the like.
Mine seems to be full of carp.

I actually reloaded Windows 7 2 weeks ago, after the problem 1st started, but I did change device manager to show hidden devices and did not see anything relevant.

USB Device Not recognized if not a hardware defect can also be a driver issue or USB power issue. Since it is a laptop it may be doing something to the USB power for battery conservation (even if the AC adaptor is plugged in). You may want to try going through the Windows power management options (try on Peformance mode, and to disable powering down of USB devices), as well as the BIOS for USB power options. Additionally try the receiver on multiple USB ports (ensure it's plugged directly into the laptop and not through a USB hub).
Since it's a fresh install of Windows it's unlikely that it's a driver issue, but not impossible, the receiver uses Microsoft USB drivers, there are a few ways to fix them, one is a system restore to a point when everything was working, a Windows Repair with Windows 7 CD/recovery partition or also you can copy the drivers (located in C:\WINDOWS\inf) from another Windows 7 computer.
