Subject: EHCI and MUSB do not discover devices without CONFIG_PM
Date: Mon, 27 Nov 2017 23:08:33 +0100	[thread overview]
Message-ID: <20171127220833.GA10070@lenoch> (raw)

Hi there,

USB hosts do not discover any connected device on OMAP3 based board
with CONFIG_PM=n. Just enabling this option is enough to restore working
behaviour. Nothing unusual in log. Tested 4.14.2 and 4.15-rc1. I know
a lot of stuff depends on CONFIG_PM, but is this expected behaviour?
Neither EHCI nor MUSB is working without CONFIG_PM.

Thank you,
	ladis
