usb hid 能否區(qū)分上位機(jī)系統(tǒng)，如win、android、linux，會有那些不一致。主要是在window和android下需要區(qū)分使用不同的報(bào)表描述符，使用同一描述符時(shí)，android下顯示鼠標(biāo)，單window下反應(yīng)不正確。打算根據(jù)上位機(jī)系統(tǒng)加載不同的配置。

把報(bào)表描述符貼出來，測試情況

您好，不同系統(tǒng)，USB枚舉的過程都是一樣的。報(bào)表描述符的處理流程不同系統(tǒng)或版本會略有區(qū)別，這個(gè)建議具體抓包看下，正常情況下是可以一套設(shè)備各系統(tǒng)全兼容。
