我司目前想通過CH554通過串口接收Android主板USB mouse事件（比如mouse 坐標(biāo)以及滾輪事件(前滾，后滾)基本功能）來實(shí)現(xiàn)對(duì)其他PC的反控功能。目前實(shí)現(xiàn)可以進(jìn)行鼠標(biāo)左邊、右鍵以及鼠標(biāo)移動(dòng)的反控，但是wheel控制時(shí)，被反控的windows端沒有反應(yīng)。目前Android下發(fā)的wheel前滾后滾事件被映射成0x01, 0xff兩個(gè)值，我這邊的報(bào)告描述符如下：

還麻煩指點(diǎn)一下wheel的控制。 PS：通過USB轉(zhuǎn)包，也能看見數(shù)據(jù)包按照report描述符進(jìn)行了上報(bào)，但是windows端對(duì)wheel沒啥反應(yīng)。

您好，

從發(fā)來的報(bào)告描述符看，

上傳的數(shù)據(jù)格式應(yīng)該是：

MOUSE_EVT_REPORT_ID? ，?Button ，Wheel ，X，X，Y，Y。

即第三個(gè)字節(jié)表示滾輪?？梢耘浜险媸堑氖髽?biāo)抓取其滾動(dòng)時(shí)的報(bào)告輔助分析問題

我確實(shí)對(duì)真實(shí)的鼠標(biāo)滾輪進(jìn)行了抓取查看，鼠標(biāo)采用的是如下的基本配置：

0x05,0x01,?//?Global?Generic?Desktop
0x09,0x02,?//?Local?Mouse
0xa1,0x01,?//?Main?app?collection
0x09,0x01,?//?Local?Pointer
0xa1,0x00,?//?Main?phy?collection
0x95,0x03,?//?Global?ReportCount
0x75,0x01,?//?Global?ReportSize
0x05,0x09,?//?Global?Button
0x19,0x01,?//?Local?Usage?Min
0x29,0x03,?//?Local?Usage?Max

0x81,0x03,?//?Main?Input(Cnsr,Var,Abs)
0x95,0x03,0x75,0x08,?//?Global?ReportCount?Global?ReportSize
0x05,0x01,?//?Global?Generic?Desktip
0x09,0x30,?//?Local?X
0x09,0x31,?//?Local?Y
0x09,0x38,?//?Locak?Wheel
0x15,0x81,?//?Global?Logical?Min
0x25,0x7f,?//?Global?Logical?Max
0x81,0x06,?//?Main?Input(Data,Var,Rel)
0xc0,??????//?Main?End?collection

我抓取了鼠標(biāo)的wheel，前滾一格0x01,后滾一格0xFF, 不滾動(dòng)0x00.??

我的CH554上也通過接收android端識(shí)別到的滾輪事件來映射了這樣的鼠標(biāo)值，但是report過去后windows端沒有滾動(dòng)。但是我又沒有辦法知道windows端的驅(qū)動(dòng)到底是如何解析的我的report信息。目前左右鍵和x,y移動(dòng)都沒問題，就是滾輪沒成功。

還麻煩能否指點(diǎn)一下其他意見或者調(diào)試方式。

這個(gè)報(bào)告描述符的格式和您發(fā)的是有區(qū)別的

后面發(fā)的這個(gè)格式最后面三個(gè)字節(jié)分別是X，Y，Wheel。而且這個(gè)報(bào)告沒有report ID。

您可以試下將報(bào)告描述符改成和它一樣的內(nèi)容，再上傳和它一樣的數(shù)據(jù)格式測(cè)試。

電腦會(huì)分析報(bào)告描述符來確定報(bào)告的格式。
