I'm working on an OMAP3530CUS board that uses an ISP1505 USB PHY, and I
haven't gotten much luck getting the kernel to recognize any USB
devices. No luck, actually. :) My oscilloscope and the schematic say
that the hardware is wired up properly, I'm just wondering if anyone has
a similar configuration that's working for them--- and which kernel they
are using?
The only thing I'm a little concerned about is the possibility that the
"nop" transceiver isn't the right one for the ISP1505. I have seen
patches floating around that claim to support the ISP1504, which should
be compatible with the 1505 if the datasheet is to be believed; but
those patches were in the context of i.MX3x machines, and they also
depended on a "slim framework for external transceivers" patch that
AFAICT hasn't been merged anywhere despite having been posted back in June.
Said patches can be found here:

Anyone have any ideas on how to pursue this, before I start chasing a
solution down myself?
is this with musb ? if it's musb, you need the nop transceiver. Do you
have any boot logs which you could share ? Without information on the
board, is a bit difficult :-(
