petesmc Posted November 30, 2012 Share Posted November 30, 2012 Hi, I purchased CMFVYGT3A-64GB and it works fine in a USB 3.0 port. WHen I tried on a USB 2.0 port it worked for about 15 seconds and then it disappeared and has never worked again on a usb 2.0 port. On usb 3.0 it still works fine. What can I do?

Toasted Posted December 1, 2012 Share Posted December 1, 2012 Do you have the latest chipset drivers installed? Please fill out your system specs. Latest BIOS? Check device manager and see if the USB is detected on the USB 2.0 port. If it is, What's the device status? Link to comment Share on other sites More sharing options...
petesmc Posted December 1, 2012 Author Share Posted December 1, 2012 Motherboard: P8Z77-V PRO Lastest bios, chipset, etc etc. Windows 8 64bit. Not recognised in a USB 2.0 port even in the bios so will definitely not be recognised in windows. Is there any tool to do a full reset of these devices as it did work for at least 15 seconds in a 2.0 port. Link to comment Share on other sites More sharing options...

petesmc Posted December 3, 2012 Author Share Posted December 3, 2012 Tried multiple PCs and Macs and nothing. Think this is a RMA? Link to comment Share on other sites More sharing options...
