If your USB is not connected to your device in some way, you cannot open a file that resides on the USB, unless the USB is connected to a networked device and you have access to that network.
it is possible for it to short the board or card it is connected to if its not running properly - so yes... if your USB port is connected directly to the main board it is possible, yes.

Check that the usb device is functional in the Device Manager, Some USB devices don't appear in Device Manager use the utility program that came bundled with the device to check for errors. No. Plug the device into another USB port. If it does not work after you have plugged it into all USB ports on the computer then you know that your device is not working.
As long as you do not have password protection on, there is a little slide tab at the non USB end of the device that has a tiny lock/unlock symbol. Slide that with a paper clip to the unlocked to turn off write protection.
First try moving the device to another USB port!!! Check that the usb device is functional in the Device Manager. some USB devices don't appear in Device Manager use the utility program that came bundled with the device to check for errors.
