Description Chen Yu 2016-12-12 03:33:26 UTC
Per ftrace result when doing suspend/resume from S3, the ax88772a_hw_reset has a  explicit msleep of 200ms in the code, is this  mandatory or can we reduce this sleep time?
usb_dev_resume -> asix_resume -> ax8872a_resume -> ax88772a_hw_reset:
msleep(200);

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
