Hi. I discovered a problem with USB host mode on a Nexus 7 running

Timur,
This mailing list is intended for discussion of the mainline Linux
kernel, rather than NVIDIA's modified (and older) downstream kernel, as
used on shipping Android devices.
Your best bet for support is to report the issue to
linux-tegra-bugs@xxxxxxxxxx. It may help if you've tried the Ubuntu/L4T
install described at:
https://wiki.ubuntu.com/Nexus7
... and reproduced the issue there too; at least some people working on
the downstream kernel do have access to Nexus 7s with that software setup.
Hi Stephen,
maybe you remember this brief conversation in December. I found the root
cause of the reported issue (tegra specific) and I can provide a patch.
The outcome is stable, externally powered USB host mode for Nexus 7.
Do you happen to know anyone responsible for the Ubuntu Nexus7 kernel? I
would like to contribute the fix, as I think it would be beneficial to
that implementation.
Thank you.
Timur
