first time I tried to connect my phone to my pc with usb cord. First it said unknown device and some how I got my pc to recognize it as my samsung. I go to my computer and it shows removable disk every time I plug the device in. when I click it tells me to insert disc. I have my.debugging on. usb settings are set for mass storage. When I connect the cord it tells me to mount and I click mount. when I connect it to my laptop it connects fine and I can transfer my files fine lap top is windows vista. The pc I am having trouble connecting to is xp. Can't figure out whats wrong
