Why not just use the usb-serial core and then you get a ttyUSB* device node "for free"? It also should provide a lot of the basic tty infrastructure and ring buffer logic all ready to use.Since I don't see how I can access same platform data from DVB USB and USB-serial driver (usb_set_intfdata). I asked that earlier, see: http://www.mail-archive.com/linux-media@vger.kernel.org/msg36027.htmlYes, and I'll have to give you the same answer as then. But, Greg, Antti makes a very valid point here. The generic code assumes that it owns intfdata, that is you cannot use it as is for access to anything that lacks its own interface. But this is not a fatal flaw. We can alter the generic code to use an accessor function the driver can provide and make it default to get/set_intfdata What do you think?
Oliver, I looked your old thread reply but I didn't catch how you meant it to happen. Could you give some small example? regards Antti -- http://palosaari.fi/
