I've got a Skybox F3 that the usb port has just suddenly stopped working. I know that others have had this problem and am wondering if anyone has managed to find the cause. Have checked the port for dry joints/continuity etc. all ok. hard drive works fine on other boxes. Have even reflashed the firmware. the hard drive light comes on and the drive spins up, usb supply voltage does seem a bit high (5.9volts). Any ideas?
