If we tested this driver as gadget, some issues below happened:
- Oops happened if g_audio.
- A usb enumeration may fail if we do insmod during connected the usb cable.
- A transaction will not finish if g_zero.
- A usb enumeration may fail after we re-connected the usb cable.
This patch serias fixes them.
This patch serias is based on Felipe's usb.git / testing/fixes branch.
