EHCI/OHCI Control Transfer Test Program

UART1 9600bps, None Parity, 8 Data Bits, 1 Stop bit, none hardware flow control
CPU at 150MHz PCI/5
USB HOST 20: SIS USB Host 20 at PCI device 1

Compiler Tool: Paradigm C++ 6.0.0 above
Project File: USBHost.ide

*******************Programming note****************************
OHCI use INTC. Type=17h, Vector=5Ch
EHCI use INTD. Type=18h, Vector=60h
OHCI Operational register memory map I/O at 801000h
EHCI Operational register memory map I/O at 800000h

This program only implement USB port0 and support high/full/low speed USB device control transfer.

*******************UART Operation Step**************************
USB high/full/low speed device attached and deattached
When device attached key "cst" in command line for doing control transfer, "csp" for stopping transfer and display information.
"ist" for Interrupt transfer, In this sample only implement "Union Star USB Keyboard"
"isos" for Isochronuous transfer, only for Logitech Webcam ,Use USB Analyzer can catch Isochronuous transfer packet.
