My external hdd from Seagate and my iphone recently started getting the message: USB device not recognized. I've tried every sulotion i could find on the internet but nothing worked yet. It doesn't work in any computer, still gets this message, it started when i changed my motherboard, and both my external hdd and my iphone was affected. The harddrive powers up and runs as usual but only gets that message, the iphone can still get power from the computer but still gets the message. So they both gets connected but cant access them, and they are shown as unkown device.
