Yes, I tested both USB2 cable + USB2 port and USB2 cable + USB3 port. In both cases it doesn't unmount the volume, just does such soft resets. Though I didn't try it for the first issue. I'll give it a try. > You really should upgrade to 3.14. I don't know whether all the > changes to xhci-hcd have been back-ported to the stable kernels. Good to know there were sizeable updates.

See the > kernel source file Documentation/usb/usbmon.txt for instructions. Is there any reason why USB3 wouldn't work with usbmon? Nothing is mentioned in the documentation itself. But yes, I'll give it a try as well. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
