Sure thing.
Thanks for your answers. So, is the computer with the logitech usb issue your machine, or your friend's?? I'm a little confused here.
Let's talk about the first machine you talked about. Make/Model of that computer please! And what version of Windows it is running currently. This shouldn't be too hard to figure out.
Just because you don't think you have any anti-virus software installed (or rather your friend), doesn't mean it's not there. If you friend's computer is running Windows XP up to and including Windows8.1; they all come with built-in anti-virus and firewall software installed on the machine as part of Windows. Depending on your friend's computer and his/her version of Windows installed, it will be either Windows Defender or Microsoft Security Essentials(MSE). In most cases, when a person buys a new laptop or desktop computer, these programs are turned ON by default. Which means until you DISABLE them, they will effectively BLOCK driver installs, even from USB peripherals such as Mice, Keyboards, and Printers without physically installing any drivers from CD disc.
Once you can let us know what your friend's computer specs are, and the version of Windows being run, I can be more specific and provide you some resource links on how to disable what's being run.
To query you further, why did your friend ask you to reinstall his/her Windows in the first place? Did you do that just to straighten out a Mouse or Keyboard issue?? Kinda like throwing the baby out with the bathwater don't you think?
Also, did you use legit Microsoft or OEM (Dell, HP, Gateway, etc.) Factory Recovery Discs to reinstall your friend's Windows? If not, and you are using a copy someone or your friend gave you, those usually do not work, as they are nearly impossible to copy, and most copies don't do a proper Windows reinstall. Your problem with usb devices could easily come from that scenario. I see that all the time and just saw it 2 weeks ago on a HP-Compaq nc8430 laptop. Customer had a "Win7 disc" in his DVD drive with no writing on it that he said was a good Win7 install disc. Turned out it wasn't; don't know where he got it from or how, or he just wasn't telling me since he suspected it was an illegal copy and may have been afraid that I was going to turn him in to the Cyber-police. He bought the laptop on ebay and tried to upgrade it from XP to Win7 himself and it failed horribly.
I'll give you some more things to try once I get more info on your friend's machine.
In the meantime, if you are not comfortable fooling around with your friend's computer, whether or not they are paying you to fix it, since you are not a professional; I'm here to tell you that he/she will hold you responsible if you scramble their laptop either way **been there, done that!**. I would strongly urge you to take it to your local licensed Computer Pro and have them look at it. Even if your friend can't afford it, YOU should pay for it, since if you mess it up--you will be held responsible, both morally and legally. And, most importantly of all: BEFORE YOU MAKE ANY MORE CHANGES TO YOUR FRIEND'S COMPUTER, MAKE SURE YOU BACKUP ALL HIS/HER PERSONAL DATA TO EXTERNAL MEDIA!!!. IF YOU DON'T KNOW HOW, YOU SHOULD PAY A TECH-SAVVY PERSON OR COMPUTER PRO TO DO FOR YOU!!
That's it for now,
