Hi all - I have a Dell S2740L 27" and a Macbook Pro 17" 2011 I have recently purchased a wired mouse and keyboard, and want to connect these two peripherals via the two USB ports, which are located at the back of the monitor. Unfortunately, when plugged in, both of these ports are not recognised. I have phoned Dell customer support early this morning and they have said that the firmware would need to be updated, but because I am not using Windows, they have stated that this issue is a compatibility one as no drivers are available for Mac systems. Just wondering if there is anyway possible I can get the wired keyboard and mouse to work via the USB ports at the back of the monitor, as the wires will not stretch to my Macbook Pro. Thanks all, -Ben.
