Michael Sauers, BCR, and a lot of books that I won't list here, covers the incredible gamut of what can be plugged into a USB (Universal Serial Bus) port. (Allows 127 devices to be hooked up to a single computer, and power can be transferred from the computer to the device; designed to be hot-swapped)
Michael is running a contest: choose the item(s) on his list/notes that doesn't really exist.
Two types: USB 1.1 (12 Mbits/sec) and USB 2.0 (faster transmission, backward compatible with 1.1)
Some things to make USB even better:
- Passive Extension Cables--available in various lengths--16 ft. length limitation; repeater/active extension cable overcomes the 16 ft. limitation (should you ever need it...)
- USB Hubs (add more USB ports)
- wireless USB hub
- USB Server--allows you to connect a hub via Ethernet so USB devices are connected to a computer, rather than a computer
So, here we go...what can be plugged into a port? (This won't be nearly as much fun as seeing the pictures of all the fun stuff--like the thumb drive (in the shape of a thumb), the USB teddy bear drive...or all the instances of each of these below, but):
- well, the extnsion cables and hubs
- the usual peripherals--mouse (incl. mouse with laser pointer and thermometer), keyboards, numeric key pads, floppy drive, printer, scanner
- storage card reader/writer (if you get one for library make sure it's reader writer)
- external drives: hard drives, hard drive enclosure, external optical (CD, DVD) drives
- flash drives
- digital music players
- video capture devices
- fingerprint scanner
- print servers
- wireless presenter
- smartphone
Well, you get the idea: just about anything can be plugged in. Why do librarians care? Because there are many that you can use to make your life or your patrons' lives easier, and/or you will see your patrons bringing this in to use on your computers.
OK, well a few more fun things: (or not??? Remember, one or more of these may not really exist...)
- lava lamp, Christmas tree
- microscope
- Swiss Army Knife with flash drive
- Skype phones, TV via Skype
- Aquarium
- humidifier, hand- and foot-warmers, air-conditioned shirt
Potential security risk? Yes (stress POTENTIAL) but security solutions:
- Deep Freeze or Centurion Guard
- Do not allow booting from the USB port (configure from BIOS...only allow boot from hard drive)
- Password protect your BIOS
- Separate the public computers from the library network
- Run antivirus software (and keep it up to date)
Proper device removal--click on the safe device removal icon in the system tray, select the device and wait for the "safe to remove" message before unplugging
