I've got a bug filed as my USB3 thumb drive in Maverick and Natty only gets detected as a USB2 device (please find some details below).

Launchpad bug record

  • Has anyone an idea how to troubleshoot that further or get it fixed?
  • Can anybody confirm USB3 devices working on an ASUS M4A88TD-V EVO/USB3 motherboard (with a NEC uPD720200 USB 3.0 onboard chip) on any of both USB3 ports?


What I've also done to troubleshoot/fix without success is:

  • checked all USB ports to be sure not to use the wrong one
  • blacklisted the usb2 kernel module (ehci_hcd) to enforce loading of usb3 kernel module (xhci_hcd) while connecting the thumb drive
  • checked different upstream kernel instead of the default Ubuntu kernel
  • checked different Ubuntu kernel (also from kernal-ppa)

Are you sure, you plugged it into an USB3-Port on your computer? Some (cheaper) pcs have both usb2 and usb3 ports. – con-f-use Jul 2 '11 at 9:31
