I'm using a Lenovo 3000 Y500 laptop. All four ports are not working.
I bought a PCMCIA card for USB. Through an USB charger I supplied power to the PCMCIA card. Now it is detecting the mouse and pen drive, it shows the message "UNRECOGNIZED DEVICE FOUND" for my external drive. When I checked "update driver", it shows the "DRIVER NOT INSTALLED" message.
The light is blinking on the hard disk, so it has power, but it's not showing anything in Windows Explorer. After some time it is showing the device type as "Initio driver controller"
I already wasted two months by repairing the USB ports. Finally it turned out to be a motherboard problem, and now PCMCIA is not supporting the external hard disk
Please check the first revision of the question. I too wasn't entirely sure what they meant with it. – slhck – 2011-12-23T14:08:58.937
