OK guys please bear with me on this one !
I am getting problems installing USB devices after i have installed active sync 3.7 i have reinstalled windows xp 3 times now and i think i can narrow the problem down to active sync.
What happens is when i try to install a USB device xp finds the device (and says what it is) but will not load the drivers for this device even if the driver has been loaded before the device has been plugged in.
This also happens when i try to use my portable USB hard drive that does not need drivers for xp it usually just loads up and works but in my case it brings up the found new hardware wizard and then says (CANNOT INSALL THIS DEVICE)
Now I know the drivers are there for the devices because they can be seen in system32/drivers but xp will not accept them.
Please note this only happens after active sync has been installed.
It does not matter what device I try to install slot card readers or printers scanners it will not find the drivers?
If I uninstall active sync it does not make any difference and I cant re install the Axim it wont recognise it !!! no matter which USB port I put it in even the one it was in.
All the devices that were installed prior to the active sync still work fine so long as you don’t plug them into another USB port if they are used in another port it gives the same problem but plug it back into its original one and its ok???
hope someone can help im getting tired of installing xp now
