Hello, While I was testing my patch to combine the dwc2/s3c-hsotg into a DRD driver, I found that after disconnecting a USB HDD from an OTG A-connector, then reconnecting it, the driver would no longer detect the USB device.
I was able to track this issue down to this commit: commit beb7e592bcfd750951c47580494f13065f0fd44c Author: Julien DELACOU <[email protected]> Date: Wed Nov 20 17:29:49 2013 +0100 staging: dwc2: add check on dwc2_core_reset return If the GRSTCTL_CSFTRST self-clearing bit never comes back to 0 for any reason, the controller is under reset state and cannot be used. It's preferable to abort initialization in such case.
