Some great ideas, good to know about the power management. I unchecked the boxes, but unfortunately, it's still not recognized. Any other ideas for Seagate FreeAgent Go? Thanks

CAUSE loadTOCNode(1, 'cause'); During initialization, devices are reset too soon after they are powered on. In this situation, some devices may use the wrong connector.

Solution:

Power Management system can sometimes cause issues. follow these instructions:

Right-click on My Computer/Properties/Hardware Tab/Device Manager. Now look for the Universal Serial Bus controllers tree....then expand it. You should see a number of USB Root Hub insertions. Right-click one of them/properties/Power Management. Take the check out of the box labeled "Allow the computer to turn off this device to save power".



If you still get "Usb device not recognized" in Windows and the above solution doesn't work for you, there might be other causes:
A) USB device worked before but suddenly stopped working:
The following solution might be applicable:

1) Remove all oem*.inf files
=
1. Click start and click run then under the run line type in the command “cmd” (without the quotation marks)
2. In the command line, type in the following (without the quotes) and press enter after each command:
“cd \windows\inf”
“ren infcache.1 *.old”
“ren oem*.inf *.old”
“del C:\windows\setupapi.log”
2) Removing all entries under HKEY_LOCAL_MACHINE/Enum/USB that start with VID ==
Removing the VID entries from the registry will cause them to be redetected at restart.
CAUTION: If you have a USB keyboard or mouse, do not remove the VID entry for these devices, otherwise, Windows may not restart correctly.
1. Click Start and click Run. Type regedit and click OK. The Registry Editor window will open.
2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB.
3. Highlight and delete all the VID_…. entries.
Permissions may be set allowing the deletion of the VID_ entries by following the steps below:
a)Right-click the key to be deleted, and then click Permissions. The VID_… Permissions window will open.
b)With Everyone highlighted in the Group or User name section, select Full Control in the Permissions section.
c)Click Apply, and then click OK.
4. Turn off the computer.
Reconnect the USB device to the computer system: ==
1. With the computer system turned off, reconnect the USB hub to the the USB port.
2.Restart the computer.
3.A New Hardware Detected window should open and reload the drivers.

My laptop doesn't recognise external hard drive


Most Windows versions:
Go to the diskmanagement (run compmgmt.msc) option Disk management.
Locate the drive and add a driveletter.
If the drive is not shown in the list, you need to check your USB drivers or connectors.

Hi I own a Samsung G3 Station External Hard Drive 2T. It was working completly fine, however just recently its screwed up. I have tried using it on all my computers and laptops.. but for some reason...


Your external drive may not be coming up due to a defected usb adapter, this might also explain why your computer fails to recognize the device. Try getting a new adapter and see if that works

Zippy USB external hard disk case (2.5


I know this is an old thread, however if it helps any one try this:
Zippys power supply failed for me also. The problem here is your case support USB 2.0 ("A high speed USB device") and your port is only USB 1.1 ("plugged into a non-HI-SPEED usb hub"). This will not give adequate power to the drive. So use a y-cable (http://www.toshibadirect.com/images/ui3/accessories/toshiba-usb-y-cable-ba82010-300.gif) and connect one end to your casing and the two pins at the other end should be connected to two USB ports. (get it at http://www.toshibadirect.com/td/b2c/adet.to?poid=438342).
Another costlier way is to upgrade to USB 2.0 by a card like this http://www.belkin.com/support/download/download.asp?category=1&lang=1&mode=
or even better a USB 3.0 card : http://www.asus.com/product.aspx?P_ID=lGYmelQ8mJvPtYTv
