Revision a7d8d1c7a7f73e780aa9ae74926ae5985b2f895f authored by Andrew Lunn on 14 June 2021, 15:55:23 UTC, committed by Greg Kroah-Hartman on 17 June 2021, 13:34:21 UTC
The Cypress CY7C65632 appears to have an issue with auto suspend and
detecting devices, not too dissimilar to the SMSC 5534B hub. It is
easiest to reproduce by connecting multiple mass storage devices to
the hub at the same time. On a Lenovo Yoga, around 1 in 3 attempts
result in the devices not being detected. It is however possible to
make them appear using lsusb -v.
Disabling autosuspend for this hub resolves the issue.
Fixes: 1208f9e1d758 ("USB: hub: Fix the broken detection of USB3 device in SMSC hub")
