I should have your recent patches up-to [PATCH] power: supply:
cpcap-charger: Enable vbus boost voltage applied to linux-next, -0830.

So... to get usb host to work even with stock kernel, I need a hub and
external power... and "right" cable between phone and hub.

When I plugged/unplugged it several times, I got

### usb unplug:
musb-hdrc.0.auto: musb_set_peripheral: already in peripheral mode: 80
musb-hdrc.0.auto: musb_set_peripheral: already in peripheral mode: 80
ub0: stop stats: rx/tx 0/0, errs 0/0
l3_init_cm:clk:0040:0: failed to disable
l3_init_cm:clk:00c0:0: failed to disable
### usb plug produces nothing
### usb unplug:
musb-hdrc.0.auto: musb_set_peripheral: already in peripheral mode: 80
musb-hdrc.0.auto: musb_set_peripheral: already in peripheral mode: 80

Hmm. I did it two more times, and now machine rebooted, and USB was
powered from the phone for a while (3.6V).

And I reproduced the crash on the next boot.

Is there anything I may be missing in .config?

Best regards,
