现象:
通过USB发送光驱弹出信号后 光驱没有弹出。
bushound显示发送数据成功。
;=================================================
问题:
是报告描述有问题,还是发送的资料不对。
;=================================================
问题发生的环境:
硬件:
【光驱是好的】
;=================================================
软件:
多媒体的报表如下:
;REPORT ID 3
db 0Ch, 09h ; usage page (consumer)
db 01h, 0A1h ; usage (remote control)
db 01h, 85h ; collection (application)
db 03h, 19h ; report id (3)
db 00h, 2Ah ; usage minimum (00)
db 3Ch, 02h ; usage maximum (572)
db 15h, 00h ; logical minimum (0)
db 26h, 3Ch ; logical maximum (572)
db 02h, 75h ; report size (16 bits each)
db 10h, 95h ; report count (1 report)
db 02h, 81h ; input (data, array, abs)
db 00h, 0C0h ; end collection
bushound抓出数据如下:
03 23 02 00 00 00 00 00 开默认主页
03 00 00 00 00 00 00 00
03 27 02 00 00 00 00 00 刷新网页
03 00 00 00 00 00 00 00
03 E9 00 00 00 00 00 00 vol+
03 00 00 00 00 00 00 00
03 EA 00 00 00 00 00 00 vol-
03 00 00 00 00 00 00 00
以上数据送给电脑后都有功能,为什么发送如下数据后不能弹出光驱呢?
光驱是好的,可以用鼠标点右键-弹出。
