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.

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

OK I have
http://git.linuxtv.org/cgit.cgi/media_tree.git/log/?h=devel-3.17-rc6
running now (reporting itself as 3.17-rc5), with the 3.40.1.0 firmware
from your site.
Both tuners work for all stations, except that the first tuning attempt
on each tuner simply doesn't lock. Doesn't seem to matter what I tune to.

I left it trying to tune for minutes, and occasionally it would get a
lock for one sample but then lose it again for the next.

:/ Sounds like a something is not initialized in a correct order. I
suspect it is it913x tuner driver. But without a hardware, I cannot do
much for it. So let it be.
Good to hear that it works that better, even first tune will fail. It is
though annoying as you will need to close app and then try again. I
suspect it needs "power on - sleep - power on" in order to init all
properly.

Well it's easy enough to work around by running dvbtune or tzap with a timeout on boot or when the device is inserted. I've had tuners with such quirks before.
Still, 3.16.3 with the 3.39 firmware didn't show this. 3.16.3 with the 3.40 firmware was quite unpredictable though.
These dongles are pretty cheap here. Do you have DVB-T to test with?
Thanks
