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 <julien.delacou@xxxxxx>

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.

Has anyone else seen this issue with the dwc2 driver on 3.14-rc1?
Thanks,
Dinh
