Fortunately for you, on Linux, the device appears as /dev/something. Open that 
device with QFile in QIODevice::Unbuffered mode, then read from it.

Your user needs to have read permissions on the device.

Usually QFile will work on block devices. But every now and then, it may 
break. If that happens, please send us a report so that we can work on it. If 
you need something urgent, you can always also use low-level calls like 
open(2) and read(2).
