Windows 7: "Device driver software was not successfully installed"

Hi everyone. I'm brand new to this forum, so hopefully I'm going about posting my problem the right way. If I'm not, please excuse the error, and let me know what I should do instead.

So the reason I'm posting in this thread is because I seem to be having the exact same problem as Wonder Reece. None of my USB ports work and I cannot install any of the optional Windows updates. For example, when I plug in one of my flash drives, I get a message saying that the driver for the device failed to install. The same thing happens with other devices. So I go out on the internet to try to solve the problem, but curiously, my NVIDIA network adapter controller is missing, so I can't get on the internet. (I'm using a different computer to post this). I previously downloaded the driver from NVIDIA's website, and it's sitting on my desktop, but it fails to reinstall every time. So bottom line, I can't install any non-Windows drivers, and nothing that I plug into a USB port works because the drivers won't install. Seems like the two issues must be related, but for the life of me, I can't figure out how.

Hopefully I'm not confusing the issue here. It just seemed so uncannily similar, that I thought I might add to the conversation. If I'm confusing matters, please tell me what the best process is to get my issue resolved, and I'll do it. Thanks!

Thanks a lot to both of you for replying.

@NoelDP: I tried the program three times, but every time it gave me the following:

Some updates were not installed

The following updates were not installed:
Hotfix for Windows (KB947821)

@ComputerGeek: I don't have the aforementioned memory stick any more, but I do have another one that doesn't work. So it may as well be the same. Here:

TeckNet USB\VID_058F&PID_3832\5&30AC598D&0&1 The drivers for this device are not installed.
USB DISK 2.0 USB\VID_13FE&PID_3600\07BA19013A4DE38B This device is not configured correctly.

@ICit2lol: Sorry I missed your reply in my last comment. I have tested the webcam on my parents' computer and it installs first time.

Not that it matters now we know it's my PC at fault, but I've only just noticed that the installation disc says "Driver (720.V6.2)" on it. So I may be incorrect in my original post, and this disc is more of a requirement than I thought. It is odd that they don't offer these drivers on the website, though. The product is 4.5/5 stars on Amazon, and while I'm sure there are better alternatives, this is still meant to be a decent (and most importantly, working) product.

@NoelDP: I can't seem to upload it here, I keep getting server errors (my ZIP folder exceeded the upload size limit, but I also tried splitting it into two folders, tried RAR format, etc and still "server error"). So I have uploaded it here: https://www.dropbox.com/s/ewueluzr2okvaaz/CBS.zip

@ComputerGeek: I can confirm that all of those files exist on my computer. Here is the File Version info:

USBSTOR.SYS: 6.1.7601.17577
usbccgp.sys: 6.1.7601.18328

Also, I've tried running the installer using "Run as Administrator" before (and again just now to double-check), and the result is the same.

If I might also add this:

Re: your flash drive problem. See How to Cleanup and Remove old USB Mass Storage Drivers. Follow the instructions and try re-connecting your flash drive

Re: Your web cam issue / Composite Device Access Denied
Let's go back and check the access permissions on these 3 files
> C:\windows\inf\usb.inf
> C:\windows\inf\usb.pnf
> C:\windows\system32\drivers\usbccgp.sys

For each file, right click->Properties->Security tab. (You'll see a snap shot for each below).

1. For usb.inf; Select on SYSTEM and then Administrators. For each selection, verify you see the 5 check marks under Allow and nothing under Deny for each selection. (We don't care about Users)
2. Check the same for usb.pnf: Select on SYSTEM and then Administrators, verify the 5 check marks under Allow and nothing under Deny. (We don't care about Users)
3. For usbccgp.sys, select TrustedInstaller. verify the 5 check marks under Allow and nothing under Deny

Bonjour,

I had exactly the same problem with a HP Webcam HD 2300 and struggled a few weeks.
Bingo ICit2lol gave the right answer after passing the 3 spy/mal/ad ware removal tools I could install the driver
without any problem and the webcam works!

Thanks a lot.
