I am having an input device problem that's interfering with my work and it has recently started occurring more frequently making it unbearable.
I have a wired Asus Mobtuo mouse and keyboard that came with my new PC about two years ago (Windows 7 64 bit, dual pentium @ 3GHz, 8GBs RAM). The keyboard and mouse don't have any visible dents either on them or their cables.
The problem started about half a year ago. Windows notified me that my mouse/keyboard have been unplugged and they became unresponsive followed by the "ping" sound notification. After a few seconds they were back on without removing or messing with them. This happened frequently but not so much to be an actual problem.
Lately though, I never hear that sound and they both become unresponsive unless I unplug them and connect them to the front USB ports if they were at the back previously or vice versa. Every time this happens I have to move both of them. The respective USB ports from which I remove them from can't be used again until I restart my PC. Other devices such as a wireless WIFI receiver and a USB stick still work on those ports. After I have connected them to my front and back USB ports and if they stop working again I have to force restart my PC losing all of my work done. An interesting point to note is that both my mouse and my keyboard are actually receiving power from the USB even though they are not working. For example my keyboard still has the "Caps Lock" icon turned on, but I can't turn it off.
Unfortunately I don't have a mouse to try which is the first logical step to combat that situation so I am asking if you have ever experienced anything like that before. I have updated every driver on my system to both their factory defaults and to their newer version if they are available to no avail.
