[linux-dvb] VP702x is now working : Not able to lock to the signal
on the given frequency

I compiled your new driver. It compiles and the driver loads OK.
"femon" runs OK, but when I run "dvbstream", it says, "Not able to
lock to the signal on the given frequency" (see details below)... and
dmesg says, "vp702x: usb in operation failed. (-110)"
This 'dvbstream' code works OK with the Twinhan VP1025 (which is
the same tuner & DVS-S decoder, but with a PCI bus) using Manu's driver:
Here's the output of dvbstream:
/home/kjh/dvbstream/dvbstream -D 2 -f 1091000 -p V -s 20000 -udp -net 10.18.10.218:1234 0 16 33 4130 4132
