我们公司的产品使用了AM1808的USB2.0接口，运行的LINUX-2.6.37，现在发现只是挂载USB2.0的U盘或者移动硬盘都没有问题，但是挂载USB3.0的设备的时候读取文件十几秒之后，USB设备就不识别了，重新插拔也挂载不上。但是USB3.0的设备在电脑上的USB2.0接口工作正常。
想问一下，是驱动的问题还是芯片没办法支持USB3.0的设备？
AM1808只支持USB1.1, USB2.0, 不支持USB3.0
请问AM1808要如何配置内核才能支持usb2.0？
我用的linux3.2.0, 内核配置的时候配置system type选TI davinci的话，后面USB驱动就找不到EHCI_HCD(USB2.0)support了。
1808不是EHCI的结构
它是MUSB
默认的就支持2.0
那么请问我应该如何配置内核呢？
system type应该怎么配？
usb driver应该怎么配？
MUSB是不是也需要配置内核配置出来呢？我没有找到相关选项啊？我用的是linux3.2.0
