External (USB 2.0) hard drive shuts down USB port and is not recognized until port is disabled and then re-enabled
External (USB 2.0) hard drive shuts down USB port and is not recognized until port is disabled and then re-enabled
- I have a 160GB Seagate Free Agent Go external drive. It requires 2 USB ports - one for power and one for power + data. Since installing Windows 7 Home Premium, whenever I plug it in to my computer (Asus Z71V notebook), the drive will light up for approximately 5 seconds and then shut off. When I looked in Device Manager, I found that the USB port to which the power + data cord was connected (as well as the USB 2.0 host controller) had been stopped by Windows because it "reported a problem." I tried several things to fix the issue and eventually found one that works - with both USB cords plugged in to the computer, if I disable the affected USB port and the USB 2.0 host controller and then re-enable them, my drive is detected and works fine.
However, the same issue happens every time I plug in the drive, and I would very much like to be able to use my external drive without needing to disable and re-enable USB ports every time I plug it in. This issue seems to be unique to Windows 7 final, as I had no problems with it in either the beta or Release Candidate versions, and I had no problems with it in Windows XP or Vista either.
Is there is a way to prevent Windows from shutting down the affected USB port so my drive can go back to being plug and play? Please let me know and thank you in advance.1 person got this answerI do too

- Thanks!
Please go into device manager. For each USB Root Hub, go to the Power tab on the Properties page and uncheck the "Allow the computer to turn off this device to save power" check box. Reboot the machine. Then try connecting the device again.
If you still hit the problem, repeat the steps above and capture another trace please.
Thanks,
Mark

- Hello,
Some additional information is needed to diagnose this issue. I'll need you to capture a USB trace for me please.
1) Reboot the machine with the drive disconnected.2) Run this command from an elevated command prompt (right click on command prompt shortcut, select "run as administrator"):
Logman start USBForumTrace -p Microsoft-Windows-USB-USBPORT -o USBForumTrace.etl -ets -nb 128 640 -bs 1283) Run this command from an elevated command prompt:
Logman update USBForumTrace -p Microsoft-Windows-USB-USBHUB -ets -nb 128 640 -bs 1284) Execute your repro scenario (in your case, plug both of the cables into the PC before plugging the other end into the drive).
5) After you have a repro of the problem, run this command from an elevated command prompt:
Logman stop USBForumTrace -ets6) Search on the machine for “USBForumTrace.etl”
7) Post that file and c:\windows\inf\setupapi.dev.log on a public folder on http://skydrive.live.com and post the link here.
Thanks,
Mark

- I too have a similar problem that is fixed when I uncheck the "Allow the computer to turn off this device to save power" box but the box is rechecked upon reboot every time. Is there a way to make this stay permanent. I have an ASUS A8N-SLI nith nforce 4.

Try this:
Control Panel -> Hardware and Sound -> Power Options -> Change plan settings (make sure you click on the link next to the currently selected plan) -> Change advanced power settings -> USB settings -> USB selective suspend setting -> Change it to disabled.
