I've a couple of Technotrend S2-4600 USB boxes successfully working on a current Ubuntu 18.04. Now I bought an additional one which is not working (/dev/dvb/adapterX/frontend0 is missing). As far as I understand this is a new brand with a new chipset - at least for windows you have to use different drivers pre and post 2018.
Ubuntu gives me the following information on boot (dmesg):
Code:
[ 1.726433] usb 1-6: Product: dvb-s2
[ 3.836725] dvb-usb: found a 'TechnoTrend TT-connect S2-4600' in warm state.
[ 3.836909] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
[ 3.838057] dvbdev: DVB: registering new adapter (TechnoTrend TT-connect S2-4600)
[ 3.841996] dvb-usb: MAC address: 00:18:bd:5b:dc:70
[ 4.166384] m88ds3103 0-0068: Unknown device. Chip_id=38
[ 4.166398] dvb-usb: no frontend was attached by 'TechnoTrend TT-connect S2-4600'
[ 4.229613] dvb-usb: schedule remote query interval to 250 msecs.
[ 4.229616] dvb-usb: TechnoTrend TT-connect S2-4600 successfully initialized and connected.
Funny but eventually just random: the Chip_id from the original hardware is expected to be 70 (M88DS3103_CHIP_ID) which is calculated from the hardware registry by a division of 2 (dev->chip_id = utmp >> 1; drivers/media/dvb-frontends/m88ds3103.c Line 1395). 0x70 is exacly the double of 0x38, so without the shift (which IS correct for pre-2018 chips)...
Is there any chance there will be a fix for this? In fact: does anyone know the difference in hardware (Technotrend Support won't tell me ).
Thanks
Jochen
