ive got a chocolate, even with no drivers windows should see it as removable media, like a flashdrive so you can move mp3s/pics to use as ringtones etc.

i would get rid of any software you put on and see if you can use it as a basic removable drive......the phones screen should go orange and say "USB do not remove" or somthing.....and it should show up as a new drive in "my computer" along side yor c drive etc.

USB 1/2.0 should make no difference.....if using usb 1 you might get a windows message saying "this device can perform faster" thats all.

make sure you plug the lead into the pc, then plug the phone in (with the flip closed)

hope that helps
