I have a Dell Inspiron 9300 with 6 USB ports running XP Media Center Edition version 2002 with SP2. When at home I have several devices connected and when on the road I disconnect them and connect others. My problem is that often when I come home I can no longer connect to the things that worked before I left home. If I remember the exact port that a device was using it might connect but not always. In device manager I now get 3 unknown devices that show up but I don't know what they are. I connect things that worked in the past and if asked for the driver I point to the CD where the driver is but is says it can't load because it doesn't have the correct software. If I delete the unknow devices with the yellow question mark they will re-appear when I scan for new hardware.
If I reload the machine and add the devices and drivers it will work until the next time I leave home. Is there a way to tell what the devices are that it thinks are connected? I am not very good at stoping USB devices before I disconnecting them, could this cause this?
I have been fighting this for months and have reloaded the OS on the machine several times
