Hi Antti, I'm using a af9035 based usb devices on mips device but may affect other usb tuner.. In dmesg I get a lot of usb 1-2: dvb_usbv2: pid_filter() failed=-929852640 usb 1-2: dvb_usbv2: pid_filter() failed=-929852640 usb 1-2: dvb_usbv2: pid_filter() failed=-929852640 usb 1-2: dvb_usbv2: pid_filter() failed=-929852640 usb 1-2: dvb_usbv2: pid_filter() failed=-929852640 This should mean that the code go into the next if.. /* activate the pid on the device pid filter */ if (adap->props->caps & DVB_USB_ADAP_HAS_PID_FILTER && adap->pid_filtering && adap->props->pid_filter) but into af9035.c code I can't find any caps initialization, pid_filtering or pid_filter. It seems like that some structure isn't initalized correctly. I can't understand if the issue is in dvb_usb_core.c that don't initialize caps.. and pid_filter* or in each dvb_usb driver that don't null the value of each structure.. Please, can you check?
