try this patch: commit d5f42190e7cf11b20face63ee96f26c7d2067b63 Author: Ming Lei <tom.leim...@gmail.com> Date: Wed Jan 5 22:03:21 2011 +0800 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.
