--53AZ357FMu84hmXL Content-Type: text/plain; charset=us-ascii Content-Disposition: inline I'm trying to set up MythTV on a 10.2-STABLE system using an RTL2832U class tuner and webcamd webcamd-4.2.0.9. The tuner probes as: Apr 27 12:36:40 tiwi devd: Executing 'logger Unknown USB device: vendor 0x0bda product 0x2838 bus uhub0' Apr 27 12:36:40 tiwi root: Unknown USB device: vendor 0x0bda product 0x2838 bus uhub0 These IDs are mentioned in https://wiki.freebsd.org/WebcamCompat, along with the comment: Needs webcamd >= 3.10.0.7; seems to be only a bit less sensitive than my dib0700 tuners (worse reception in low-signal areas); remotes not supported yet by the Linux rtl28xxu driver and thus by webcamd; also supported by the comms/dabstick-radio and comms/rtl-sdr ports I run webcamd with the invocation: webcamd -N RTL2838UHIDIR-Realtek -S 00000001 -M 0 -v 0 -B This creates the devices: # ls -lR /dev/dvb/ total 1 dr-xr-xr-x 2 root wheel 512 27 Apr 17:54 adapter0 /dev/dvb/adapter0: total 0 crw-rw---- 1 webcamd webcamd 0x95 27 Apr 17:54 demux0 crw-rw---- 1 webcamd webcamd 0x96 27 Apr 17:54 dvr0 crw-rw---- 1 webcamd webcamd 0x97 27 Apr 17:54 frontend0 When I run mythtv-setup and try to access the tuner, I get the messages: 2016-04-27 17:27:43.168109 W DiSEqCDevTree: No device tree for cardid 1 2016-04-27 17:27:57.021513 W DiSEqCDevTree: No device tree for cardid 1 ktrace tells me: 3391 mythtv-setup CALL openat(AT_FDCWD,0x8608eb598,0x2<O_RDWR>,<unused>0) 3391 mythtv-setup NAMI "/dev/dvb/adapter0/frontend0" 3391 mythtv-setup RET _umtx_op -1 errno 60 Operation timed out ... 3391 mythtv-setup CALL write(0x1,0x7fffdfbfb640,0x49) 3391 mythtv-setup GIO fd 1 wrote 73 bytes "2016-04-27 17:04:39.188786 W DiSEqCDevTree: No device tree for cardid 1 " 3391 mythtv-setup RET write 73/0x49 There's nothing of importance between the attempt to open /dev/dvb/adapter0/frontend0 and the error message, so clearly that's the reason for the message, even if it's not quite appropriate. I don't see any mention of rtl28xxu in current documentation, and no way to specify a driver in the man page. Can I assume that this is an undocumented change? Any ideas how to corner the problem?
