Chapter 1 Required Hardware and Software The TUSB3410 general-purpose input-output EVM was designed for use with a personal computer running a USB-enabled operating system. The PC should be USB 1.1 or USB 2.0 spec compliant. This implies the BIOS, chip- sets, and operating system are all spec compliant. If the BIOS is not spec com- pliant, the system may not boot when USB devices are connected at power up and the EVM may not function. Note that the EVM can only function in the bus-powered mode
