Hi Felipe & Kishon, Looks like musb is broken at least on pandaboard es in current linux next while it works with v3.6: [ 1.933074] musb-hdrc: version 6.0, ?dma?, otg (peripheral+host) [ 1.939422] unable to find transceiver of type USB2 PHYrouping on. Total pages: 251648 [ 1.945190] HS USB OTG: no transceiver configured [ 1.950134] musb-hdrc musb-hdrc.0: musb_init_controller failed with status -19 [ 1.958160] couldn't find an available UDC I do have CONFIG_OMAP_USB2 set. Note that we won't be able to flip omap4 over to be device tree only probably until v3.9 because of the bindings we're still missing from usability point of view. So this regression should be fixed. Also on the EHCI port, I've seen issues where unplugging the cable hangs kernel with an infinite loop. But that happens only occasionally, sorry does not seem to happen right now so no output to paste here. Or maybe this issue has already been fixed?
