["corp\\KChen" <keqiang.chen@windriver.com>]

Dear Manager,

I am debugging a platform with SI470x FM radio module(Usb interface).
The linux kernel version is 2.6.35.7.
I have configured the linux kernel and it can recognize this module.
But there are some abnormal log and I cant scan the FM channel normally.
