[Bug 625162] Re: USB HDD spontaneously spews read errors/hub enumeration errors, gets unmounted

[Yang]

Unplugging the device and plugging it back in didn't made this appear in
syslog:

Aug 27 01:01:18 zs kernel: [1146943.041430] ehci_hcd 0000:00:1d.7: port
4 reset error -110

Pulling the power and plugging it back in brought things back to normal
- I can now access my files:
