0035 ; This is the Cypress USB Keyboard + PS2 Mouse demonstration firmware.
0035 ; It supports the following features:
0035 ; - Ch. 9 and HIDView compliance
0035 ; - String Descriptors
0035 ; - Suspend / Resume / Remote Wakeup
0035 ; - Send keys on change
0035 ; - N-Key rollover
0035 ; - Debounce
0035 ; - Phantom keys
0035 ; - Boot protocol
0035 ; - Plug and Play PS/2 Mouse Port
0035 ;
0035 ;REVISIONS:
0035 ;08/17/99 bth rewrote endpoint 0 ISR
0035 ;02/02/99
0035 ; bth added set idle, get idle for mouse/power keys
0035 ; added boot protocol switching on 2nd endpoint (mouse/power)
0035 ; added get_report for mouse and power key packets
0035 ; altered mechanism for maintaining idle period
0035 ; by removing it from ISR and placing it in SendKeyboardReport
0035 ;11/09/98 bth added power management support
