Kagem Yohanes,
* A Low Speed (1.0) rate of 1.5 Mbit/s (192 KB/s) that is mostly used for
Human Interface Devices (HID) such as keyboards, mice, and joysticks.
* A Full Speed (1.1) rate of 12 Mbit/s (1.5 MB/s). Full Speed was the
fastest rate before the USB 2.0 specification and many devices fall back to
Full Speed. Full Speed devices divide the USB bandwidth between them in a
first-come first-served basis and it is not uncommon to run out of bandwidth
with several isochronous devices. All USB Hubs support Full Speed.
* A Hi-Speed (2.0) rate of 480 Mbit/s (60 MB/s).
