Re: Raspberry Pi Zero W almost useless

Hello Lwazi,

Thanks for the tip. I know how to recompile a kernel but I doubt I
could do such modification in the source with chances of success
without knowing the internals of driver programming. ;-) Only know the
basics of C.

I have been watching /usr/src/dev/usb/usbdevs and it seems easy to
change. Then it says that usbdevs.h will be regenerated automatically.

I believe that  I have to add the following line with the RTL8188FTV
product ID (Realtek vendor ID  is ok in the usbdevs file):

product REALTEK RTL8188FTV 0xf179 Realtek RTL8188FTV

The problem is to change /usr/src/dev/usb/if_urtwn.c  without knowing
what I am exactly  doing  ;-)

Another thing I am thinking about is the firmware...

Too few chances of success, I think.
