Unfortunately, drivers for specific devices will probably still need to<br>
run in kernel-space.<br>

NetBSD has it.  Noone else does.  For once, BSD beats Linux in hardware<br>
support.  Weird... :-)<br>
<p>
People tell me that USB is somewhat like a cross between SCSI and<br>
Ethernet - devices and host adaptors are adressable nodes on a bus,<br>
and can send messages and data to each other using a defined protocol.<br>
<p>
Right away, that sounds *way* better than parallel or serial ports.<br>

<p>
Alphas and Amigas...  not much else.  (Some PowerPCs, too, such as the<br>
BeBox and PPeP/PReP/CHRP boxen)<br>
