蓝牙鼠标HID

gason

请问一下，在同样CPU使用率高的情况下，如在空闲CPU为：40%时，我本人开发的蓝牙鼠标移动时有出现卡与丢掉数据情况，而在市面买 回来的蓝牙鼠标却不会，一切都正常？
      我开发的鼠标端口是已经是中断传输的了，还不知为什么会卡，请高手指点？

baiheee

是否是蓝牙传输环节有问题？可以用排除法，直接用接收端模拟发USB鼠标数据看有这种情况没有

gason

谢谢，可以试一试。

gason

还是不行的，不知什么原因

baiheee

用接收端直接模拟鼠标数据也是同样现象？

gason

是的. 谢谢。

设备的各种描述符发上来看看，以及设备枚举时的数据也抓下来看看，你自己也可以比较一下枚举的数据是否正确

现在如果网页上打开网络教程，也会卡卡的。
我把相关设置发上来，请你帮看看》
我的驱动是在TI上面作小修改，只是改了设备名称。

我的驱动是在TI上面作小修 ...

大概看了下，TI原示例应该是个复合HID设备（复合鼠标和键盘），你做的是鼠标，那最好不用复合设备，把键盘去掉，不防试试

gason

不过同样是复合的鼠标和键盘的另一家厂做的HID，却不会出现卡的问题。
