Hi Steven,
I'm CCing Linux-wireless as they might be able to help and I'm running
out of ideas =)

This really looks like a hardware issue. Maybe your ath9k_htc device
is particularly sensitive to power supply noise or something like
that. Have you tried a different power supply or connecting it through
a powered hub?
I really wish I could help out more with this =)
I'd be surprised if it's a software issue, but if you're compiling
your own kernels, it might be worth checking out the Linux Backports
project:
https://backports.wiki.kernel.org/index.php/Main_Page
Which is essentially the latest kernel's WiFi drivers and stuff
repackaged so it can be compiled with older kernels.
Thanks,

That can be an issue. After firmware is loaded power consumption goes
from 30mA to 100-200mA. If it won't get enough power, then it will get
strange issues. Second problem is noise on data or power lines. It
depend on circuit design, cable and so on. Some users reported similar
issues which was fixed after cable change.

Yea... i will not continue this discussion untill you get updated driver.

I already am on the latest firmware. But, we can stop all this. Self-powered hub did the trick! The funny thing is that I already tried with the hub and as far as I remember didn't change much.
Anyway, thank you very much for your time and your sharp eye Julian. Indeed this was hardware related.
Thank you all,
Steven
