I have a client with an XP home PC (major brand so support forums easy to check)- SP3, up to date, with current mainstream Anti Virus, with an odd USB problem.
I have checked previous posts with similar titles and tried a selection of the suggestions provided all without relief from the problem.
Issue – Clients own USB devices work, Clients USB Flash drives work, Clients Ipod works, a new phone obtained recently when connected searched for a USB driver with the error message ‘Data Invalid’, USB inserted reports driver not installed properly.
Device Manager shows all built in hubs working but with the recently inserted USB device yellowed out. Other ports show driver correctly installed, put her USB stick device in while this disabled device connected and it works perfectly so driver installed and not missing. Other device still dead.
All hubs deleted along with all relevant USBStor files, after a restart the situation as as before.
I have tested the power output to the various USB ports and the useable ones all have a power rating of 100 or 200mA which I know is below the required 500mA. So I suspect it’s a faulty USB controller with the already recognised devices OK but all new unpowered USB memory sticks and even my Ipod (as USB file store) is unrecognised. So here am I with my bootable USB drive holding an image of the drivers am unable to load the files required to effect a driver reload.
Does anyone have similar error messages and an obvious repair that I am missing?
I did suspect virus activity but online scans only found the usual tracking cookies and associated Ad ware. Registry is now clean and optimised, Drive defragged and scanned no issues yet.
I am reluctant to do anything major to the system
