The Uses of USB
Ideal Uses
• Most human input devices: bar code, buttons, digitizers, gaming, gloves, joy-
sticks, keyboards, knobs, light-pens, mice, 6-axis, tablets, trackballs, touch-pads
• Modem & telephony: POTS, FAX, ISDN, T1, ADSL, low-end cable modem
• Printers, up through 40 ppm or so
• Simple audio: MIDI, speakers, mono&stereo I/O, 5.1 compressed surround out-
put (moving the audio codec outside the box has benefits but overhead hazards)
• Low-demand imaging: digital still cameras, low-rate and/or low-resolution
motion video (e.g. conferencing), monitor calibrators, custom displays, monitor
control
• External floppy drives (FDD, LS-120, HiFD, ZIP)
• Legacy adaptors (USB-IR, USB-serial, USB-parallel, USB-PS/2)
• Security authentication: biometric input, dongles, intrusion detection
• Power management: UPS, cryo-cooler control
Hot-attach/detach permits simple (albeit break-before-make) console switching,
and the 5m segment length can handle most server rack situations.
