USB

Known USB Devices

Devices that are being built with the USB architecture include:

  • Telephones
  • Modems
  • Keyboards
  • Mice
  • CD-ROM drives (up to about 6x due to bus bandwidth limitations)
  • Joysticks
  • Tape drives
  • Floppy drives
  • Scanners
  • Printers

The Windows 98 implementation of the USB specification supports up to 127 simultaneous devices. Segment lengths between devices and hubs or host controllers can be up to 5 meters. Devices such as scanners, cameras and digital speakers are slated to use 12 Mpbs while other devices; mice, keyboards, etc. will use the slower 1.5 Mbps rate to communicate.

The USB specification defines a standardized connector and socket which all peripherals can use, thus eliminating the existing mixture of connector types. All connectors should also have the USB icon (shown below) on the connector. This icon will also appear in device manger next to USB controllers, devices and hubs.
