Toshiba laptop, USB problem & Windows 7

  AmyL 11:35 30 Jul 2011


As the title says I have a Toshiba Satellite L450D-13X laptop. It has Windows 7 and is a 64-bit system (I believe - I am not very knowledgeable when it comes to computers!). For some time my USB memory stick hasn't worked on it, in fact I can't remember if it ever did or just on my old laptop. Then I noticed my iPod won't charge or be read at all either. I believe another memory stick did once work so does this just mean these 2 items aren't compatible or something?

I also bought a CNM external HDD from on a good deal but it won't work as the USB ports don't read it. I'm sure it detected 'new hardware found' at first but then nothing, you can't even find the USB ports in 'Computer'. I looked on the box and it seems only to be compatible with 32-bit systems.

Will I need to convert the laptop to 32-bit to get everything working or is there some other problem?

Thanks in advance!

Right Click on My Computer/Properties/Hardware Tab/Device Manager. Go to USB at bottom Left expand then Select one USB at a time the press uninstall do this for all USB. Then Restart your Laptop.. When it restarts it will start the Found Hardware Wizard, it will then reload all your USB's do not have anything plugged into any USB when you do this. then try them after it as reloaded all

Ok thanks, I did this but it hasn't come up with the 'Found Hardware Wizard'...nothing, just started as normal. What should I do to re-install them?

Remove all USB devices

Download and run click here USBDeview

Uninstall ALL devices that are shown as not connected.

Reboot the machine.

Plug in your USB device and windows should then find new hardware and reinstall the drivers for the device.

Ok thanks, done, but still not detecting any USBs I plug in.

Re the HDD will I need to buy one that specifically works for 64-bit? Is this the same with any USB device?

Have a look in device manager what is it showing under the heading USB?

HDD should make no difference whether 64 or 32 bit

This is the list under USB:

Standard Enhanced PCI to USB Host Controller (x 2) Standard OpenHCD USB Host Controller (x 4) USB Root Hub (x 6)

Try Disconnect all USB devices

In device manager Uninstall EVERYTHING under the heading USB, reboot the PC let windows find and install new hardware.

then plug in your USB equipment, should now be recognised.

Re external HD. I also have a Toshiba, and a mains power HD is fine, but a portable has 2 x USB connections to get enough power. The portable HD I bought han a double USB connector.(iomega 500 gig portable HD)
