Hi, as nobody answered my email regarding the LiveView TV Walker, I'll assume that nobody is interested in it :) Well, I'm am, so I am looking for basic steps to develop support for it. I've been looking around the dbv wiki (a lot, believe me), but I'v not found any quick-tutorial/basic steps for developing/adapting/extending a driver (sorry if that information is there, but I've not found it). But, from the information in different pages, I've figured out a general approach I'm trying to take in the next days (please, any help will be welcome): 1. Get the device working on Windows (it already works) 2. Get *lots* of USB-sniffing info for the device 3. Analyze *lots* of that information in order to detect and identify: 3.1 Control commands send from the windows driver to the device 3.2 Responses from the device to the driver 4. Try to create a new driver from an existing one, replacing the device-specific messages/behaviour with the one outlined by the usb-sniff analysis 5. Compile, insmod, cross my fingers... Is that more or less OK? If so, any hint will be welcome regarding: * The best approach for USB snoop traces generation/analysis. Maybe think about possible actions in the windows interface and try to get a separated snoop trace of each one of them? (ex. plug-unplug the device [don't know if it's possible], scan channels, select a channel, ask for the EPG, ask for teletext). That is: for each "action": start snooping, perform the action in the windows interface, stop snooping, keep log file and analyse it later (I know it's a rough assumption, but I guess it should be easier to locate that information in a file that reflects "only" one specific action that in a big big file with lots of action mixed up together) * What do you think is the best driver to take as a basis/template? (emXXX?) * Firmware... uh? I've been that in order to work with some devices, it is needed to download some firmware to them. How can I know if I need to do it with my device or not? (snooping usb also?) I know this message could contain some "dumb" assumptions / questions, but *really*, i'ts been a long time since my last kernel development (a dummy device driver, kind of "/proc" filesystem): **eleven** years ago (yes, the time from boot/root floppies ;) ), so forgive me for any imprecission/assumption/stupid question in the whole mail.
