Performance issues are fixed recently (at least I hope so), but it will
took some time in order to get fixes in stable. Unfortunately I don't
have any IT9135 BX (ver 2 chip) dual device to test like yours...
Could you install that kernel tree:
http://git.linuxtv.org/cgit.cgi/media_tree.git/log/?h=devel-3.17-rc6
and firmwares from there:
http://palosaari.fi/linux/v4l-dvb/firmware/IT9135/ITE_3.25.0.0/
and test?
regards

I have a new Leadtek DTV dongle dual (usb 0413:6a05). With linux 3.16.3
the first adapter tunes and works fine, but the second tuner will only
tune to the one UHF multiplex in our area. The other five multiplexes
are all VHF and it won't lock on any of those.
Here's the kernel log from inserting the device;

Here's an attempt to tune a VHF station with tzap; w_scan only finds the
UHF multiplex. Note it's adapter 2 and 3, as I have a leadtek PCI card
at adapters 0 and 1.

Is this a known problem, and is there a solution?
