I have been using my laptop, Acer ASPIRE 4752 for about 2 years and it has been working like a charm, except that its USB 3.0 port is malfunctioning. The weird thing is, the port does have power since i can charge my cellphone using a USB cable slotted to the port, but it cannot read my harddisk. My harddisk can be read using my other 2 USB 2.0 ports. It does not even exist in my device manager. <br /> <br /><img src='http://s22.postimg.org/cza8klwtd/device_manager.jpg' border='0' alt='user posted image' /> <br /> <br />As i checked in the Control Panel, the 'Renesas Electronics USB 3.0 Host Controller Driver' has already been installed <br /> <br /><img src='http://s18.postimg.org/umnrvs8u1/device_manager.jpg' border='0' alt='user posted image' /> <br /> <br />I have also enabled the process for startup <br /> <br /><img src='http://s21.postimg.org/xhybxun9z/device_manager.jpg' border='0' alt='user posted image' /> <br /> <br />I have tried restoring my laptop to factory setting and it obviously is not working. please help! amadmizi Technical Support Sat, 27 Dec 2014 19:12:09 +0800
