Missing musb-hdrc module required by Pandaboard OTG port

From Precise omap4 kernel config:
ubuntu@panda1:~$ fgrep MUSB /boot/config-3.2.0-1405-omap4
# CONFIG_USB_MUSB_HDRC is not set

From Oneiric (config-3.0.0-1207-omap4):
CONFIG_USB_MUSB_HDRC=y

Rebuilding the kernel with module built-in similar to Oneiric works. The OTG port is detected without issues.

could you test this kernel?

http://people.canonical.com/~ppisati/linux-image-3.2.0-1406-omap4_3.2.0-1406.9~lp927860_armel.deb

This kernel doesn't work either. May need to be built-in or it may need some other missing bits to enable.

modprobe musb-hdrc
FATAL: Error inserting musb_hdrc (/lib/modules/3.2.0-1406-omap4/kernel/drivers/usb/musb/musb_hdrc.ko): No such device

Would be possible to compile an armhf kernel. I am currently running armhf and so unable to test it.

I am not sure if this is helpful, I have a kernel that I compiled from source. I build all the modules I need loaded into the kernel, my personal preference.

$ cat /boot/config-3.2.1-omap4 | grep -i musb
CONFIG_USB_MUSB_HDRC=y
# CONFIG_USB_MUSB_TUSB6010 is not set
CONFIG_USB_MUSB_OMAP2PLUS=y
# CONFIG_USB_MUSB_AM35X is not set
# CONFIG_MUSB_PIO_ONLY is not set
CONFIG_USB_GADGET_MUSB_HDRC=y

This from your build

$ cat config-3.2.0-1406-omap4 | grep -i musb
CONFIG_USB_MUSB_HDRC=m
CONFIG_USB_MUSB_TUSB6010=m
CONFIG_USB_MUSB_OMAP2PLUS=m
# CONFIG_USB_MUSB_AM35X is not set
CONFIG_MUSB_PIO_ONLY=y
# CONFIG_USB_GADGET_MUSB_HDRC is not set

I think CONFIG_USB_GADGET_MUSB_HDRC is required for it to work.

here it is, an armel and armhf flavour with USB_GADGET_MUSB_HDRC:

I installed the kernel and the device is being detected:

$ uname -r

The kernel that I had built earlier
