Making it Work
What we know:
- it uses parts/all of the ttusb-USB-protocol
- isochronous Data transfer (whole TS only)
- no firmware is needed (budget device)
Drivers
The following drivers are needed for these devices:
- stb0899.ko - stb6100.ko - lnbp22.ko - dvb-usb.ko - dvb-usb-pctv452e.ko
To use this device you have to have a tuning application that uses the new multiproto DVB api. there's a patched version of szap available (search mailing list).
Make sure you haven't loaded any old dvb drivers. Here's a step by step howto:
mkdir 3650 cd 3650 hg clone http://jusst.de/hg/multiproto wget http://hem.passagen.se/faruks/3650/pctv452e.patch patch -p0 < pctv452e.patch cd multiproto make ; # there might be a few warnings. cd v4l insmod dvb-core.ko insmod dvb-pll.ko insmod stb6100.ko verbose=0 insmod stb0899.ko verbose=0 insmod lnbp22.ko insmod dvb-usb.ko insmod dvb-usb-pctv452e.ko # If you use 32-bit system and insmod complains about: error inserting 'stb0899.ko': -1 Unknown symbol in module. Edit this file: multiproto/linux/drivers/media/dvb/frontends/stb0899_algo.c change line 1547 from: offsetfreq = (s32)((s64)offsetfreq * ((s64)internal->master_clk / (s64)1000000) / ((s64)((1 << 30) / (s64)1000))); To: offsetfreq = ((((offsetfreq / 1024) * 1000) / (1<<7)) * (s32)(internal->master_clk/1000000)) / (s32)(1<<13);
