You have not said how you created those files, but if there is
/absolutely/ nothing added to dmesg when you plug it in then it must
be broken (or the usb socket on the PC is broken).  I suggest keeping
it simple and just running dmesg, noting the last messages, plugging
it in and running dmesg again.  Even if the kernel does not recognise
the id it would still notice that something had been plugged in.
