I have not been able to identify this part.
Tried both visible light and strong UV light.

Did check a few semi-conductor catalogs for a six pin device with D- and D+ run to those pins, without any luck.
Which just means that I couldn't find it, not that it isn't in someones catalog.

What I did not check was application notes from Freescale.
They might have something with recommended parts to use on the OTG port.
