How old is your laptop? older laptop will only support USB 1.1 and newer USB devices also will only work with the newer USB 2.0 ports! Most newer USB 2.0 memory sticks/flash drive are USB1.1 downwards compatibe. Bottom line: check what USB version is supported by your Laptop and your plug-in device! Also note that your Laptop BIOS should have LEGACY USB SUPPORT ENABLED and your device, especially if a Media Player, should have its operating MODE set to mimic a FLASH DRIVE (otherwise it will be an unknown device to 'my computer' drive list).
