No. The PHY chip and the musb in SoC obviously can talk to the hub, otherwise the vendor/product ids were not visible. I *honestly* doubt musb-hw on SoC has a problem like "I decide to cripple parts of data from device in HARDWARE because I'm in the wrong mode". In expression this is a SOFTWARE problem, not a hardware configuration issue.

And seriously - I thought we're thru with ID pin once and for all.

The above details show that driver is NOT in hostmode, but it still operates as a OTG device. We need to fix that - rather than any ID pin detection.
