Windows 7 laptop making phantom device insert/remove sounds
Something strange is happening to my laptop.
Every minute or so, I get the ‘duh-DUH’ two-tone sound of a device being unplugged. Then the same again, 3 seconds later (ie. unplugged – not inserted – BOTH times). Just before it, my machine/pointer freezes for a split second.
It could be a hardware/software issue, so, for the record:
Hardware: HP Elitebook 8440p, 8GB RAM, MS mouse in the USB and that’s it
OS: Windows 7 64-bit
I have had some issues with a USB modem recently – Vodafone E505(?) by Huawei, which royally messed up my USB drivers: if I plug it in, then any USB device inserted afterwards isn’t detected. However, I think I may have had this problem before this… just that it’s becoming more frequent.
Nothing in any event logs, as far as I can see; annoying; I’d have thought device insert/unplug would be an obvious candidate for logging.
I’ve also just noticed that sometimes the sound doesn’t occur for almost 5 minutes.. and sometimes there’s only one, rather than a pair in sequence.
It seems it was my mouse. I have a basic MS Optical Mouse, that I admittedly bash around a bit. I unplugged this, and, an hour later, not a peep from my laptop.
