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

[Ken Harris]

 	Patrick:

 	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:
