I have Windows XP. I can't install my Verizon Broadband card because it says I'm missing USBSTOR. SYS, so I'm here to download to fix this problem. How do I do that?

What is the body which must be 4-60000 characters?

Hello BJKW,

Thank you for your message.  What service pack you have installed?  You can check this by running the following steps:
Click 'Start' > right click on 'My computer' > select 'properties '.
Diet: You should see Microsoft Windows XP... Service Pack?

If you do not have Service Pack 3, you must perform updates of Windows until you are completely up to date.  To do this, follow the steps below:
Click 'Start' > select 'control panel '.
Double-click on "Security Center."
On the top left, click on "Find the latest updates from Windows Update"
If you already have service pack 3, we will check to see if this file is located in your system.
Click 'Start' > select 'search '.
Click 'All files and folders' > 'all or part of the file name', type USBSTOR. SYS and click on "search".
The file is located?
If so, is it in c:\Windows\Driver Cache\i386\sp3.cab?  If this isn't the case, you will need to move it there.
Please let us know if it did or did not solve your problem.
See you soon
