I mentioned it in the context of dib0700 because that is the device the user is experiencing the issue with, as well as the only device in the dvb_usb framework I am personally familiar with. Regarding lirc, this is a challenging issue: On one hand, it is logical for the remote control definitions to be in userland, as this allows the user to change the keymaps easily, and the IR receiver could be seen by the kernel as "just another RC5 or RC6 receiver". On the other hand, the in-kernel management allows it to work as it did before without the need for lirc, as well as allowing the driver implementer to provide the "default keymap" associated with the remote control that ships with the product. If the keymaps were in the lirc userland package then the developer would have to ensure that the userland package got updated in all the distributions, as well as the users getting lircd to work properly (which given the debugging in the daemon, is an *enormous* challenge for most users). At this point, I think the goal should be to get as many of the drivers as possible centralized into ir_keymaps. This allows the drivers to behave consistently, and if we can come up with a userland solution then it can be supported for every device at the same time. Devin -- Devin J.
