TeVii S660 USB DVB-S2 working?

Hi! Is anyone using a TeVii S660 USB DVB-S2 receiver?

I'm using webcamd 5.3.7.1_1 on 12.1-RELEASE and webcamd says:
Code:
Attached to ugen1.3[0]
Loading firmware at '/boot/modules/dvb-usb-s660.fw', f=8
Creating /dev/dvb/adapter0/demux0
Creating /dev/dvb/adapter0/dvr0
Creating /dev/dvb/adapter0/frontend0
Creating /dev/lirc0
Creating /dev/input/event2

But when I try w_scan, I get:
Code:
w_scan -c GB -fs -s S28E2 -a0 -C UTF-8
w_scan version 20170107 (compiled for DVB API 5.10)
using settings for 28.2 east Astra 2E/F + Eutelsat 28A
scan type SATELLITE, channellist 62
output format vdr-2.0
output charset 'UTF-8'
-_-_-_-_ Getting frontend capabilities-_-_-_-_ 
main:4019: FATAL: FE_GET_INFO failed: 6 Device not configured

And webcamd says:
Code:
Loading firmware at '/boot/modules/dvb-fe-ds3000.fw', f=8
Bus error

Am I out of luck with this device?

If so, I see some alternatives on the WebcamCompat wiki but personal recommendations are welcome. Thanks!
 
See if there is a *.core file somewhere.
Open it with gdb91 webcamd webcamd.core
Then enter:
bt

And post the output.
 
Hi, thanks for the replies. Here's the gdb output. I notice that the code block is for M88TS2022 whereas I think this TeVii S660 is M88TS2020 - but perhaps that is not relevent.

I see that the write address is not aligned like it should for a 64-bit write:
(0x207b31de & 7) != 0

Try to type in GDB:
frame 0
print *_gain
 
gdb says:

It's a Wandboard Dual running FreeBSD-12.1-RELEASE-arm-armv7-WANDBOARD. I was able to successfully configure a DVB-T tuner on the Wandboard, so I thought the TeVii might not be compatible with FreeBSD.

But I have just tried FreeBSD-12.1-RELEASE-arm64-aarch64-RPI3 and w_scan on the TeVii worked. As I am not tied to the Wandboard, I can use the Pi instead. Thanks for questioning the architecture!
 
It is a bug in the Linux code. Should probably be reported upstream Linux!
I just sent the Linux guys an e-mail, and let's see if someone will pick it up.
