USB 1.1
USB support must be compiled into the kernel or as a loadable module. USB support is available for PIIX4 and later I/O controllers from Intel, including the Intel® 800 and 900 series chipsets. You must also select USB support for your USB component, such as a mouse or printer.

USB hubs are automatically supported.

USB filesystem support, which enables hot-swapping and dynamic detection, must also be enabled. The simplest method is to add the following line to your /etc/fstab file:

none /proc/bus/usb usbdevfs defaults 0 0

USB 2.0
USB 2.0 is backward compatible with USB 1.1. All USB 2.0 (480 Mbit/sec) devices can be used at full USB 1.1 speed (12 Mbit/sec) in all current Linux kernels. If you have the EHCI driver and a USB 2.0 host controller, then you can use USB 2.0 devices at USB 2.0 speed.

EHCI support was implemented in the Linux 2.5.2 development kernel; support was backported into the Linux 2.4.19 production kernels. The USB implementation is an ongoing project; most issues have been resolved with the 2.6.x kernels (or later).
