Today I'm contacted because another Win7 machine is not picking up any USB flash drives all of a sudden (open to interpretation). Only saw two updates that were done before the user disabled the updates on this computer due to bandwidth constraints. Did the standard trouble shooting over the phone but had to remote into the machine in the end. I checked all the permissions mentioned, and then a few extra, but everything seemed 100% fine. Images edited as required: First did a scan for new hardware: But that failed: Device manager does pick up the drives ("Jump Drive") but presents with a nice little yellow triangle.
Wireless keyboard/mouse is connected via USB and working fine.
External 3TB drive is connected via USB already and working fine.
CPU Product Name and Number: HP Pavillion a6700y Monitor: HP w2207h Operating system: Windows Vista 64-bit.
You could try sfc /scannow which will replace the system files with known good copies (you will need your Windows cd/dvd and will probably have to update some drivers afterwards) Yeah, sorry to be the bearer of bad news but that's what I'd be looking to do.
It could be a corrupted if non-storage based USB devices work ok.
