Hi,
Last week I discovered the new configfs for the USB gadget support in
the kernel.
I found the following threads on the mailing list:
https://lkml.org/lkml/2012/6/21/154
https://lkml.org/lkml/2012/11/26/38
Now there is some discussion about having a userpace library to handle
the creation
The documentation for the USB gadget fs is actually in
Documentation/usb/gadget_configfs.txt.

usb-serial-simple uses an unknown stringify macro that make
all drivers being named "stringify(vendor)".
This can be a problem when two drivers have the same (wrong) name:
kernel: usbcore: registered new interface driver usb_serial_simple
kernel: usbserial: USB Seria
