Hi!
I'm trying to port the support patches for an OMAP3530 based
development kit by Technexion.
Technexion provides patches for PSP kernel trees, I need to use a
kernel with modern IR stack, so I'm developing against
linux-omap-2.6.git
I'm mostly done with the initial port, however, I'm stuck with the
following issue:
[ 2.991973] ehci-omap ehci-omap.0: port 2 full speed --> companion
[ 2.992034] ehci-omap ehci-omap.0: GetStatus port:2 status 003801 0
ACK POWER OWNER sig=j CONNECT
[ 2.992095] hub 1-0:1.0: port 2 not reset yet, waiting 50ms
[ 3.055511] asoc: twl4030-hifi <-> omap-mcbsp-dai.1 mapping ok
[ 3.061920] ehci-omap ehci-omap.0: GetStatus port:2 status 003002 0

[ 3.061981] hub 1-0:1.0: unable to enumerate USB device on port 2
[ 3.068389] hub 1-0:1.0: state 7 ports 3 chg 0000 evt 0004
I would gladly welcome any pointers that could help me solve this issue.
you're connecting a FS/LS device to EHCI port, that doesn't work. OMAP
can't handle port handoff to companion OHCI controller, then it fails
not being able to enumerate the device. Try remuxing your port to OHCI
controller and disabling EHCI from Kconfig.
You should be using ohci-omap3.c driver.
