I am running Windows XP on a laptop (HP Compaq). It is about 2 years old.
The problem is as follows:
Whenever I plug in a USB device to any port (I have 4), it does not show up in MyComputer as a drive. This is the case with any USB memory keys I have and also with my iPod. This is a recent problem, and they all worked fine up to a week ago. The USB devices are fine as they work on other computers.
There is power going to the devices as the light on them lights up when they are plugged in. Also they show up in my taskbar to show I have plugged in a device.
I checked the Device Manager (Contol Panel / Administrative Tools / Computer Management / Device Manager) and it shows up as a Disk Drive with the type of USB storage device it is.
It does not show up in Disk Management (just my DVR drive). I went through the USB connections on the USB controllers and disabled each one and re-endabled it again and separately checked for hardware changes but still no joy.
Any ideas on what to do next?
