  • I think it's pretty clear that they used the lower power spec on the 5755. I'm not saying they are violating the USB 3.0 standard, I'm just disappointed that they chose to skimp on that (while not really informing anyone - yep you cannot find this spec from anyone and I only figured this whole thing out by accident).
  • Update: I ended up trying one last thing before going to Acer for support. I thought that perhaps not enough power was being supplied by my USB 3.0 port to the drive, forcing it to "downshift" to 2.0. So I bought a Y-cable for $5 to provide auxiliary power from the adjacent 2.0 port. Result: IT WORKS. Immediately connected…
  • Well, if there are no other ideas... looks like I am going to pay for out-of-warranty Acer support. Thankfully my SquareTrade warranty will reimburse me for it. I bet they're going to make me reinstall Windows even though I've replicated the issue under a totally different OS.
  • Results: Safe mode = same deal Clean boot = same deal and, incredibly... Ubuntu 13.10 Live USB environment = same deal!!! The 3.0 USB controller is recognized and active, yet when I plug in this WD drive it is rerouted to the USB 2.0 hub, actually the same hub that runs the USB 2.0 port right next to it. At this point I'm…
  • Microsoft support actually had a great idea - to try the drive under Safe Mode, and then to try a Clean Boot. I am giving those a shot tomorrow morning, and I'll also try to boot into a Ubuntu Live USB to try it through there - hopefully there will be a compatible USB 3.0 driver available for Ubuntu.
  • I really appreciate you trying to help!
  • The way I removed the drivers was by sorting by connection in device manager, which shows you the entire USB controller with the devices under it. I removed the whole thing, no trace of USB left. The only issue I see is that, because the laptop has a built-in webcam, as soon as the computer reboots it does in fact seem to…
  • Could the Renesas driver be storingg information somewhere about devices it has seen that is separate from the windows registry? I've completely uninstalled and re-installed the driver and all associated software at every step.
  • Amazing, that didn't work either. I currently have no USB 2.0 driver installed (confirmed because when I plug something into a USB 2.0 port nothing happens). I installed the USB 3.0 driver alone, then plugged in the WD drive... and once again it installed as USB 2.0. No clue how to proceed.
  • I just used USBOblivion to supposedly remove all trace of USB drives, then reinstalled it, and it behaves the same. At this point I think I will try uninstalling every USB driver in the system. Next step will be reinstalling Windows.
  • Thanks, just tried that, didn't fix the issue. However, I'm not entirely sure I removed the right driver. I removed the Renesas USB 3.0 driver as there was no other driver that was obviously associated with my external drive. Many of the drivers had fairly generic names ("Intel" etc). Should I just completely remove every…
  • It gets weirder: I connected the aforementioned WD drive to the USB 3.0 port on a different computer. It immediately worked on USB 3.0 with the correct speeds (~140 MB/s). I connected a DIFFERENT USB 3.0 drive to my Acer's USB 3.0 port... It also works. So, for some reason, the WD drive + my Acer = fail. Now I really think…
