<itdaniher>
naobsd: I got things working, some part of my config was broken
<itdaniher>
and yes, I'm not unfamiliar with standard debugging procedures
<itdaniher>
on a different note, has anyone observed USB instability when using a hub?
<itdaniher>
rk3188 stops receiving control transfer ACKs after some period of use with a USB hub
<itdaniher>
requiring the device in question to be manually unplugged / replugged
<itdaniher>
without a USB hub, it functions fine - always receives ACKs
<itdaniher>
I suspect this is related to the issues discussed on the r'pi and fonera forums concerning the DWC_OTG driver in conjunction with a USB hub - limited number of "host channels"

<naobsd>
itdaniher: I think dwc otg driver in RK source should have some issues, e.g. it doesn't accept unaligned buffer
<naobsd>
btw control transfer may not be used so much after (per-)device initialization, which device are you using?
