Compliance compatability of the USB Hub CY7C65113
Is it possible to connect a USB 2.0 compliant FULL SPEED device to USB 1.1 compliant HUB?
Yes, you can connect a USB 2.0 compliant device to a USB 1.1 compliant hub. USB 2.0 compliant devices are backwards compatible with USB 1.1 devices. The USB 1.1 is an old revision of the USB specification. USB 1.0 and 1.1 are part of the USB 2.0 specification but, the 2.0 version of the specification, has added high-speed USB as an option.
