I am having problems with my receiver basically resetting every so often. The lights will go out on it, and the keyboard/mouse will be unusable for a few seconds. It's pretty random how often it happens, it can be as little as in 1 second intervals, or as long as 5 minutes. Anyway, I will usually just wait until it comes back and continue typing/using my mouse. Sometimes, of course, the lights never come back on, and I have to either unplug/replug the USB plug, or pick a different plug. I've tried it on every plug in my system, to no avail. If it helps, I looked at the device manager, and while the receiver was resetting, the mouse and keyboard devices became hidden.
Here are the system specs in question:
MS Wireless comfort desktop (I'm not sure which version, the box got thrown away). The versions for the components are as follows:
Microsoft Wireless Optical Desktop Receiver 3.0A
Microsoft Wirelss Comfort Keyboard 1.0A
Microsoft Wireless Laser Mouse 6000
EVGA 122-CK-NF68 Mobo (nForce 680i SLI chipset)
Windows XP SP2
I saw a similar question elsewhere, with "accepted" solutions, but the guy's problem was never actually solved, he was forced to use PS/2. I went ahead and bought a USB hub to help stabilize the power, in case it was too much power draw, but I am still having the problem, though admittedly a bit less frequently.
The keyboard/mouse still works on my old computer, which uses a Abit AX8 mobo and Windows XP SP2. No problems with resets on that one.
Also, when I run my Gentoo Linux 2006.1 LiveCD, the Xorg + gnome desktop never has this problem. My receiver stays on 100% of the time.
