Maybe this can help you:
https://garage.maemo.org/plugins/ggit/browse.php/?p=kernel-power;a=blob;f=kernel-power-2.6.28/debian/patches/usbhostmode.diff
Patch for 2.6.28 omap1 kernel which adds usb host mode support for Nokia
N900. Look for MUSB_TESTMODE, MUSB_TEST_FORCE_HOST is called together
with MUSB_TEST_FORCE_FS or MUSB_TEST_FORCE_HS (line 355).
