tried it now with a powerd usb-hub ... same results.

comment:2 Changed 5 years ago by josef.krinzinger@…

Is there anything i can do to debug this problem? Some debug-flags i can activate?

comment:3 Changed 5 years ago by lkoe <openwrt@…>

I can reproduce the same behavior with different USB devices, the root hub always gets disabled after some time being connected to an external hub. This seems to be a bug in dwc_otg.

Is there any way to debug this or to port some patches from the raspberry pi guys, that also seem to have a lot problems with this driver?

I'm using version Barrier Braker r34122 from trunk.
