Well try this with the Sony CD in a CD/DVD drive go into the System Tools Right Click on the Sony Device and chose Update Driver. Then when the next window opens chose the Find Driver Automaticly and allow the system to run until it finishes.

If it comes up with an error message you then do have something loaded that is preventing the driver being installed and it will be a painful exercise working out what it is. But if you followed the installation directions properly and didn't have the MP3 Player plugged into the computer when the Hardware driver was installed 99 times out of 100 it will work. This most often happens when people don't follow the directions and install the driver with the player attached.

If you did that you'll need to uninstall all the Driver Software that came with the Device and then proceed to reinstall it without the device connected.

Well what happened?

There are several things on the installation CD did you install the Driver? and not just the software?

If you still have that yellow mark beside the device in Device Manager what else have you got installed in the way of Hardware and Software as there has to be something conflicting with it and not allowing a Registry Key to be activated.

If nothing works then post back with the actually hardware you are using and that means every plug in Card and all installed software.

I take it that you have checked that the USB ports are actually working right?

Col

is it usb ? if so try to plug something else into that same port and see if it works. if it does work try downloading the updated driver from sony. if the usb does not work, check to see if it is disabled in cmos.
