usb drivers

[Kalyan Kodamagula]

Hi,

  Iam new to this ML,I need info regarding Usb device drivers.I had learned Lnx device drivers and having
 knowledge on USB Host driver(highlevel).

  I had seen probe/read/write functions of a driver.As there is no need to write drivers from scratch,we can gain knowledge by fixing some bugs in the driver.

Can some one please give me links/doc to see the bugs and related fixes of USB drivers.

BR.
