Shutdown when external device plugged in to usb port
My PC runs fine but when I plug in external hardware, instead of auto detecting and prompting me what options I have, the PC just shuts down and then restarts. It continues to do this until I have unplugged the external device !! Please help.
Re: Shutdown when external device plugged in to usb port
First, make sure that the external hard drive is not causing this by simply trying it in another computer. Now let's assume you dod this and it works fine in another computer, do the following: Right-click on My Computer, click on Properties, click on the advanced tab, click the Settings button where it says Startup and Recovery, then uncheck the Automatically Restart under System failure. The next time you plug the hard drive it will not restart but it will let you see the error message if any.

im assuming its the round ps/2 purple port you are refering to. the simplest solution would be to boot your computer up without it plugged in and when a complete bootup has finished. plug in a usb keyboard. the system will detect new hardware and will prompt you that the device has been installed and ready to use.
replacing the original port will require a new socket and a service tech capable of soldering the piece in place. the first option is about a 10.00 fix. replacing the actual socket could be in excess of 75 or 80.00.
No problem as to which port you plug in, but make sure the Com port/RS-232/USB Port is enabled to detect the hardware. The device won't detect the hardware if you haven't made the changes in BIOS or port enabled in device manager (system properties>hardware). Hope this solves the query.
is it only one or all usb ports that doesn't work. Check your device manager and see if the Usb device are still working or the computer is able to detect it. If it is, and is able to detect and display your Usb ports then they should be working alright. There has been a virus that been going on lately that cause the computer not to read device detected to the usb ports since I had this same promblem before and it wasn't a hardware issue, but a viral issue. Had to run the latest definition and then formated my laptop to factory default.
Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.
The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.
Follow the steps given below to refresh USB ports.
1. Right-click My Computer icon on the desktop, and then select Properties. 2. Click the Hardware tab. 3. Click the Device Manager Button. 4. Click the plus (+) sign to the left of Universal Serial Bus controllers. 5. Right-click the device listed under Universal Serial Bus controller and select Uninstall. 6. Click OK to confirm the removal of the device.
Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.
7. Shut down the computer.
CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.
8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.
The above steps will refresh the USB ports.
Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.
Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate. The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below: =========================== 1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.
2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.
3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.
4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).
5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.
What you have is power over USB which is good because it allows the hard drive to get enough power to run without a seperate power cord. This is also usefull for IPODS and other media that Charge through a USB. It means you can turn your computer off and still charge something.
If its an external hard drive, its meant to be removed. You can right click and disconnect it from the bottom right and then remove it safely.
You may have a port that doesnt provide power when turned off, maybe a front USB port, you could plug it in there.
There most likely isnt a way to change any jumpers unless your system board instructions specify that you can and how to. Dont go tinkering around because if you put jumpers on the wrong spot, you can blow some of the small components on the board.
This would render the USB completely useless.
If you want a permanent extar HDD for back up, just get a new IDE for the internal, There cheep these days. you can get a 250 gig IDE for under $60.00
Did your question get answered? (I'm not sure what "no thanks" was in response to.)
Your flash drives should work fine w/ Windows XP. They should be detected by the operating system as mass storage devices - plug-n-play - w/ no need for drivers installtion, etc.
You may, however, experience detection issues w/ them on systems w/ older USB hardware. If the flash drives are USB 2.0 drives, they will not be detected on systems running USB 1.1 or earlier - regardless of the OS (operating system) installed.
On the other hand, if they are USB 1.1 flash drives, they should be detected fine on both older and newer USB ports as USB 2.0 is "backward compatible".
