Nothing wrong with SCSI; it's just that scanners seem to be stretching the design for it a bit. My SCSI scanner is the slowest, flakiest device on my SCSI bus. I don't like being afraid to burn CDs while scanning because the the bus is tied up. I also had to rearrange the internal cabling on my system to keep the SCSI bus inside the SCSI length limits after adding an external cable to reach the scanner. And having a wide->narrow transition in the middle of the bus worries me as well. If you don't put a slow, flaky device on your system bus, you have to have a separate controller for the thing - which means you are dedicating a slot and possibly an IRQ just for it, which seems ridiculous. Finally, my SCSI BIOS doesn't handle hot swappable devices. If the scanner is off when I boot, the controller won't see it, and a reboot is required to use the thing, which I find disgusting. USB seems to be an improvement in all these areas. One shared IRQ, no slots. Good support for relatively slow devices like keyboards and modems, and for bulk transfer devices like printers and scanners. It also supports plugging and unplugging the things while they are hot. <mike > Mike Meyer wrote: > > > Jason Corcoran <jason@corcoran.tc> types: > > > List, > > > > > > I have checked the handbook, but I was just wondering, during the boot process > > > my USB mustek scanner is recognised.
