Had anybody got their USB 3 ports working on E6440? I've been searching and found this text from the Dell forum: After many months fighting with DELL , from loading different drivers, to newer bios. I reloaded windows completely, i have tried factory defaults, nothing worked, DELL came out and replaced the system board twice. still to no avail. failure.. FINALLY! DELL agreed to replaced the entire laptop. I received a "REFURBISHED" laptop with RMA. I Have plugged in all 3.0 USB ports with USB 3.0 devices , its been days now and no issues. all 3 work flawlessly! no drop outs, no hiccups. My old laptop was REV 1.0 on the system board this one is REV 2.0 IF your laptop is under warranty.. DEMAND a replacement. as this was the ONLY fix i found. My MOBO is rev 0. Anybody has similar problems?
