And both are USB 3.0 ports according to the Thinkpad X240's specs. Since Tim hinted, that some USB 3.0 ports are not 100% compatible (and I can confirm that faulty USB 3.0 implementations exist), I would suggest to try it on a computer with USB 2.x ports, instead.

Alternatively, you may be able to work around problems by disabling the USB 3.0 drivers in your operating system.

Good luck,
