Give some general info how these sticks are are build on a level chips are interconnected, from the driver developer point of view. One thing what I have tried to tell is how to gather needed information using some common reverse-engineering techniques, needed by about every Linux developer working with these devices. One thing I would like to do is demodulator reverse-engineering tutorial. Unfortunately I haven't found suitable example yet, as it should be some DVB USB device having existing drivers for USB interface and RF tuner, and simple USB protocol. EC100/EC168 is one very good example, but unfortunately I have done its driver ages back. Maybe I should rewrite it from the scratch :) > http://www.kernellabs.com/blog/?page_id=2066 Especially I like to read those articles related of sniffing hardware directly from the bus (I2C, IF, ...). > > but if I found even more .... > > > I think it would be a good idea if anyone > in the vger.kernel.org list could provide his blog's ( website) address > so that we can share knowledge together. > What do you think? regards Antti -- http://palosaari.fi/
