1.1 Required Hardware and Software
The USB keyboard/hub EVM is designed for use with a personal computer
running a USB-enabled operating system. The PC, with BIOS, chipsets, and
operating system, should be USB 1.1 or 2.0 specification-compliant. If the
BIOS is not compliant, the system may not boot when USB devices are
connected at power up, and the EVM may not function. Additionally, one or
more low- or full-speed USB devices are needed to plug into the downstream
ports of the USB keyboard/hub EVM to exercise the hub ports. A standard USB
cable is needed to connect the USB keyboard/hub EVM to a downstream port
of the PC or a USB hub tier.
