Hi greg k-h, Thank you for your reply. I have tested older kernels (4.12> and 4.9 LTS) but unfortunately the device is still unable to scan any channels. It also has difficulties with getting a stable connection when using a static/preloaded frequency/channel instead. It's a bit strange, but I believe it worked on kernels before <4.9 but KP were more frequently, so I'm happy with the changes made. Yesterday I have tried the media_build of CrazyCat (https://bitbucket.org/CrazyCat/media_build.git) on top of Linux 4.12 and this works fine. I'm not aware of the cause, but running a diff on drivers/media/usb/dvb-usb/cxusb.c (https://github.com/crazycat69/linux_media/blob/latest/drivers/media/usb/dvb-usb/cxusb.c) it seems the following lines may be missing: memset(&si2168_config, 0, sizeof(si2168_config)); memset(&si2157_config, 0, sizeof(si2157_config)); If more debug info is useful and may help finding the cause, I'm happy to provide. Thanks again for looking at the issue.
