try this patch:
commit d5f42190e7cf11b20face63ee96f26c7d2067b63

arm: omap4: panda: remove usb_nop_xceiv_register(v1)
Panda uses both twl6030 otg phy(vbus, id) and internal
phy(data lines, DP/DM), so removes usb_nop_xceiv_register to make
twl6030 otg driver working since current otg code only supports
one global transceiver. Otherwise, musb doesn't work without
the remove.
