0049 ; - String Descriptors
0049 ; - Suspend / Resume / Remote Wakeup
0049 ; - Send keys on change
0049 ; - N-Key rollover
0049 ; - Debounce
0049 ; - Phantom keys
0049 ; - Boot protocol
0049 ; - Plug and Play PS/2 Mouse Port

0049 ;REVISIONS:
0049 ;08/17/99 bth rewrote endpoint 0 ISR
0049 ;02/02/99
0049 ; bth added set idle, get idle for mouse/power keys
0049 ; added boot protocol switching on 2nd endpoint (mouse/power)
0049 ; added get_report for mouse and power key packets
0049 ; altered mechanism for maintaining idle period
0049 ; by removing it from ISR and placing it in SendKeyboardReport
0049 ;11/09/98 bth added power management support
