What it's being made illegal is also personal recording conversations of which you are part. This is legal in most of civilized world, since is a mere documentation of facts you already know by being present.

USB is PIO and not DMA? You understand that PIO/DMA transfer modes only meaningful for Parallel ATA devices?
That's because the ATA interface was originally THE 16-bit system bus (AT bus) and the disk controller was onboard on the disks (thus the name IDE - Integrated Drive Electronics).
So, the CPU accessed the disk controller through the AT bus which was originally programmed I/O and then started using DMA.
Of course, the system bus quicky become different and faster (FSB + PCI) thus the ATA interface became a disk attachment interface instead of the system bus and an additional controller was put between the system and the disk.
USB is a completely different beast. The "bus" actually transfer packets (URBs) and all USB controllers use DMA to transfer URBs to the main memory... So, no PIO/DMA stuff is involved....
