There is a new version of the TechnoTrend CT2-4400 USB tuner. The difference is the demodulator that is used (Si2168-B40 instead of -A30). For TT CT2-4400v2 a TS stream related parameter needs to be set, otherwise the stream becomes corrupted. The Windows driver for both CT2-4400 and CT2-4400v2 sets this as well. After this patch the driver works for both versions. Signed-off-by: Olli Salonen <olli.salonen@iki.fi> --- drivers/media/usb/dvb-usb/cxusb.c | 6 ++++++ 1 file changed, 6 insertions(+)
