Re: usb port problem

It's possible that your PC is not receiving adequate power from the power supply unit (PSU) to power everthing in use and the USB devices that you are attempting to connect. The USB port provides power as well as data connection. If you know it, what is the rating of the power supply unit in your computer?

PSU's are easy to upgrade, and some stores will let you return them if that's now what you need. (CompUSA (R.I.P.) was my favorite for troubleshooting repairs. By it, test it, bring it back if it wasn't the fix you needed.) Find someone you know/trust who know's what they're doing, or bring your CPU to a PC repair facility and let them test your computer and do the needed repair/upgrade there. Just be ready to spend a few more bucks.

Hope that helps. Let us know how you make out.

Recently, when I insert a USB flash drive into my laptop's USB port, I get the message: This USB device can perform faster if you connect it to a HI-SPEED USB 2.0 port.

Your laptop has USB1 port and the USB 2 message will appear if you plug an USB 2 device into this USB port.
You maybe able to upgrade the USB port to USB 2 if there is a BIOS upgrade available from the laptop manufacturer's WEB site.
If not you maybe able to get an USB 2 PCMCIA card to install into the PCMCAI slot on your laptop.

My usb ports suddenly stop working...i plug and unplug my mouse and it works for seconds...then again stops...and again and again and again the same thing...

make sure the battery is good ((has full charge))also you make sure the usb device for the mouse is inserted correctly into the usb port (if applicable) or if its a lead
make sure the lead from the mouse has a secure seating and the lead is not bad/faulty
((if applicable)) if this fails to fix the problem you could try it in safe mode
restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer
click start control panel administrive tools computer management device manager scroll to mice and other pointing devices you might see a yellow exclamation mark ! or question mark ? or a red x right click to update driver
if your computer came with a motherboard disk the driver could be on it
hope this helps

Welcome to Fixya

If the hardware you purchased came with a software or driver disk. Install it first. Test the USB port. Try to insert other USB device other than your 1 TB HD. If the USB port was able to detect other device, then the problem is your 1 TB drive. If USB port were not able to detect other USB device, then the problem is your USB 3.0 card.

Thank you for using Fixya!

Where on the reader do I insert an Olympus xd picture card (M512 MB) ?

An USB memeory card reader should have several slots to insert the various memory cards.
You insert the memory card into the correct slot on the card reader and then connect the CARD reader with the USB cable into the USB port on your computer.
The computer will see this as an external storage device, you can then copy the photos off the memory card into your computer.

My memory card does not format and has msdc can i format it in windows xp because when i try to it brings windows can not format the disc.


If your computer affected by virus,then your memory card will not show in the pc .so you will install it to another pc,and format it .Flash drive can not recocknize,becayse there are some reason .

  • VIrus affected
  • Sometimes when a flash memory stick or USB external hard drive fails because it was not removed from the USB port properly. If the device is removed by just pulling it out of the USB port, it can cause the flash device to fail, you must click on the Safely Remove Hardware icon on the Task Bar and select the device you wish to remove and only do so when instructed to do so.

When the flash memory USB hard drive device appears to malfunction it may be possible to restore it by reformatting it. Insert the flash or USB hard drive into the USB port then Click on Control Panel - Administrative Tools - Computer Management - Disk Management.
Then right click on Disk 1 removable drive and click Format. After the flash drive has been formatted then it will indicate that it is Healthy.

If this doesn't work then it is faulty.

hope it will help you
