broken. There's a patch to fix client mode, but host mode still isn't

Host mode musb is working just fine on Overo with the "set
transceiver" patch.  Not sure why you are having trouble with Beagle
(and can't check since I don't have my Beagle board with me at the
moment)

work in 2.6.26. I haven't tried specifying pure hostmode, only OTG.

looking really, really bad on omap3 at the moment.

I should clarify: OTG mode with a host cable doesn't work in .27rc, it does I would try it on the evm as well, but that is having serious irq issues with .27rc, pressing a key on the keypad triggers an irq overrun, ethernet gives an oops on boot when trying to register and irq etc,etc. 2.6.27 is

this patch yet cuz I've been quite busy at work, but it should make
beagle work. Could you tell me if makes it work ?

Yeah, we lost some musb history when it went to mainline. I didn't test @@ -215,12 +215,14 @@ void musb_platform_set_mode(struct musb *musb, u8 musb_mode)

That looks like http://gitweb.openembedded.net/?p=org.openembedded.dev.git;a=blob;f=packages/linux/linux-omap/musb-mru-otgfix.diff;h=767858b8b1580ed7cd67d8e7627301600dda111c;hb=d733dd05e030a67dfbf4540fa1a041adccbe4ffc which doesn't work for me :(

And, no, I'm not going to try omapzoom stuff, I want it working on the canonical linux-omap kernel, not some corporate version with god knows how many hacks.
