In the case of USB_STORAGE we need to turn on DM_USB and then it works.
If DM_USB is enabled, no USB controller are detected, so we loose Ethernet. Did I miss an additional option to enable?
AFASK, the MUSB driver didn't yet support gadget mode when used with DM_USB... at least until recently. I noticed that part of the MUSB driver was updated, but the omap2430 glue hasn't been updated yet. I am not 100% sure, but I think the Beagle xM is a DM3730 which uses the omap2430 glue. I doubt TI will update the omap2430 glue, so I started some stuff. I've got on patch that seems to show the usb gadget controller in the DM tree, but my board hangs when I try to use a gadget.
It's not ready for the mailing list yet, but I can push this stuff to my github later today if someone wants to look at it and/or test/improve it.
Guillaume,
I 'think' I got the peripheral mode working on my DM3730. Like before, it only supports host or gadget, and I set the patch up to look at whether or not CONFIG_USB_MUSB_GADGET is set.
I was able to get Fastboot devices to appear and an sdp device to appear. I wasn't setup to actually run data through those interfaces, but my host machine recognized them.
Feel free to try the patches and please give feedback. They are located: https://patchwork.ozlabs.org/project/uboot/list/?series=82418
