multiple DVB-T usb tuner failure

[lage-sjoblom]

Hi all.
I hope this is the right place for this post. If not, let me know.
I have 2 DVB-T usb sticks that i can´t get to coexist.
One is an noname based on the Afatech AF9015 chip, the other one is a PCTV nanoStick T2 290e based on Sony CXD2820R.
Running ubuntu server 13.10 and TVHeadend3.4.27 on a VIA Artigo.
On the same server i also run OWFS and som 1-wire temp sensors via a Dallas Semiconductor DS1490F 2-in-1 Fob, 1-Wire adapter.
Whe i run them one at a time it works fine, but when both are plugged in, i get syslog filled with this after a while:

When i stop TVheadend, the log flooding ends.
I have the latest fw for the AF9015.
After reading some other thread i also tried adding this to /etc/modprobe.d/dvb-options.conf

options dvb_usb_v2 disable_rc_polling=1
options rc_core disable_rc_polling=1

but with no result.

If anyone can point me in the right direction to solve this, I´d be very greatful.

Lage

Are they on the same USB controller? And if yes, have you tried to connect them to different ones? (If possible)

There are 4 usb ports available, but moving them around doesn´t seem to change much. Maybe they share the same controller? Not sure how to tell...
This is how it looks after a reboot:

Hmm, not sure what's going on, as everything works independently, I doubt that it is software problem. I know that DVB-S cards and sticks suck a lot of electricity. Could it be that that two of them pull too much? Do you have the opportunity to use a USB hub with a separate power supply? I would try to connect them to a hub, or at least one of them.

Do the sticks work individually on any of the USB ports?

[lage-sjoblom]

Yes, as i mentioned in the first post running them one at a time works fine, so maybe it´s a power issue. Don´t have a hub so i can´t test now but I´ll get one.

What I meant was, does every stick work in every USB port? (there are ports with high and low current)

-Emily

[lage-sjoblom]

Yes, they do.

Hi

I am having the exact issue? Was there ever a solution to this???

Thanks
