--- This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

There are two connection settings in USB: MTP and MSC. For some reason MTP is the default, but it doesn't connect properly on all computers. Select MSC and plug the player in again, the computer will recognize sansa e250 but not show the driver just yet. It is installing recognition software (just basic drivers - nothing heavy) and it doesnt tell you what its doing until its complete. WAIT FOR IT. Once it is complete you will see both the sansa e250 and the removable memory slot in your "my computer" now you're good to go.

It is not on your computor you have to go to settings on the player scroll down to usb mode and change it there. I did and I still can not get it to be reconized. I am still having trouble get my computor to see it, it just says that it is unknown decive.

I'm wondering if its your computer. I would test another usb-connected device (i.e digital camera, USB memory stick etc.) to see if it takes that long to recognize. Also i would check what version of usb you have (ver 1.1 versus 2.0) The speed difference in both initial recognition and file transfer is significant.
