usb otg驱动问题
本帖最后由 thzhr2009 于 2014-01-13 21:09 编辑CPU:博通BCM5892
kernel：2.6.32
问题描述：otg驱动使用dwc_otg驱动模块,在加载了otg驱动：
insmod bcm589x-dwccom.ko
insmod bcm589x-otg.ko
后，usb host正常（插u盘可正常读取）；usb device有问题，通过usb线（一头为miniusb，另一位usb口）连PC，可检测到硬件接入，但无法识别，显示“无法识别的USB设备”：用bus hound捕获到的插入pc时的数据如下：

请问有没有做过otg驱动的朋友，指点下此问题。 你好，你U盘连接是好的，证明该driver对OTG 你好，U盘连接能正常识别，那么说明OTG的functions是OK的。但是通过USB连接PC的时候，有问题。那这就不是OTG的问题了。这个是USB设备驱动的问题了。
你用bus hound 来抓取的数据，应该可以很明确的看到是否枚举成的阿？如果枚举成功，从bus hound可以看到device的USB device 描述信息的。
1， 你确认下是否枚举成功？把bus hound里面刚开始插入USB device抓取的log贴出来看一下把。
2， PC端是否已经正确安装driver?此时你的 USB是工作在什么function mode?
