I created the file and rebooted with the drive connecte. The reboot
restored the Autosuspend to good.

The drive is not recognized.

I set Autosuspend to bad with powertop

 > sudo lsusb -v

The drive led blinks and the drive is in dmesg

I disconnected the drive and dmesg shows the disconnect.

I reconnected the drive and dmesg does not show the drive
