I'd strongly suggest you to try out current linux-omap code [1] and check if it works fine. Also increase MUSB_LOGLEVEL to 3 in your .config file and reabuild that 2.6.22.18 kernel. When you clone linux omap with: $ git clone http://www.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git You can make omap3_evm_defconfig and later make menuconfig to choose the gadget driver you want.
