S545 Shows up as HID Complient Device, and USB input Device

[headbangindblackburn]

I was messing around with my S545 last night, and I discovered something really strange. If you put the hold switch on and hold the option button down, then plug it into the computer, in device manager it shows up as an HID-complient device, and a USB input device. What could this mean? I'm also curious as to whether or not rockbox will ever be on this device. Is it possible? Or is the firmware too encrypted to even try?
