Hi, Attached is a latest version of "alternative" driver for the TerratecCinergy T2 USB device. The driver is heavily based on existing Cinergy T2driver but it has been modified to fit more or less into the DVB-USBdriver framework like most of the other USB-based device drivers currentlyincluded in kernel. This version also has the remote control support merged back into the driver.I'm very interested in hearing any kinds of comments about the driver. The RC support has been implemented differently compared to the standardDVB-USB-framework way, as the Cinergy T2 is capable of delivering multipleRC key event codes on a single USB-message and the standardrc_query-callback system didn't seem to be able to handle this. ThereforeI was forced to copy & modify the RC support from the DVB-USB frameoworkto better suit the Cinergy T2 needs.If you have better ideas how to implement the support more standard way,I'd be interested to hear about you. The patch below applies to reasonably current HG V4L-DVB repository tree.
