Why are you using such an old, support-less kernel ? Try with current 2.6.26 out of git repository. I've been using musb driver on omap3 for months now and it's working quite ok besides a few bugs hidden here and there (which I'm looking at). ps: this list has moved to [email protected] and musb driver is now being discussed in [EMAIL PROTECTED] mailing list, so please, care to Cc both lists mentioned here. -- Best Regards, Felipe Balbi [EMAIL PROTECTED] -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
