USB Problem

Ive bought a usb floppy drive with a card reader, and it detect fine every time when I boot up, but when you press the reset button on the pc, it doesnt detect it untill you either unplug the floopy and plug it back in again, or you have to turn the power off at the psu and turn it back on again...

It happens sometimes with other usb devices I have too.

Why is this happening....

I may be wrong here but I think you should detach "hot swapable" device correctly from the device tab that appears in your system tray before physically disconnecting. These devices are detected whilst windows is active. That said, I have an external H/D that is always plugged in and works fine?

I have a similiar problem with my USB mouse, when it was plugged into the front USB ports it would need to be unplugged and plugged back in again, but sometimes it works without this. I havent sat down and had a look at why this is. I would suggest buying a USB extension cable and plugging it into the rear USB ports if it is not already.

Hey there, I used to have this problem with my keyboard, but it was only once ever few weeks or so. I'm not sure if this will help but if you go to control panel, then system, and then the hardware tab and going into device manager.

From here look for Universal Serial Bus controllers and double click each USB root hub, go to the power management tab and uncheck the box that says "Allow the comptuer to turn off this device to save power". Do this with all the usb root hubs.

This worked for me and I no longer get annoyed at fishing at the back of my computer for the correct usb plug.
