I have a problem with my USB ports not recognising various hard drives, an iphone and a card reader which all worked perfectly up until yesterday. When I connect any of these items I get a pop-up saying “One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it.” This happens with any USB port and any cable and with all my USB devices with storage. My keyboard, mouse and printer work without problem in any of the ports.
Sometimes, with a few reboots I can get a device working for a while, but then it disappears and I get the above message.
In device manager, the offending port shows up with a yellow exclamation mark and the properties state “Windows has stopped this device because it has reported problems. (Code 43) I’ve tried uninstalling and letting Windows reinstall for only temporary cure.
I am running Windows 7 Home Premium 32bit and have made no hardware or software changes recently apart from installing the latest version of itunes. I have run a virus and malware scan which found nothing.
I did a system restore back to the weekend, as I had installed some windows updates but the problem persists.
I have tried the cures suggested to nellerose44. No joy!
I am at my wit’s end as I can’t work out whether this is a hardware or Windows problem. Any help would be much appreciated.
