I read that thread. Unfortunately I'm not a hardware engineer nor do I have access to a logic analyser, just the device and a remote hope not to keep my custom 4.13 kernel forever or to have to buy a new DVB T2 device. :( In the above thread it is mentioned that even the Windows driver receives the ffff's so maybe it is a hardware bug? I'd love to see this driver upstream but I have no idea how to proceed. Any suggestions? -- g
