Alan and Sarah, Tonight I received a Transcend USB 3,0 ExpressCard Adapter. I booted the 2.6.37-rc5-git3 kernel I built, plugged the ExpressCard Adapter into my W510, and the USB2.0 Flash memory stick into one of the slots of the ExpressCard Adapter. The Transcend USB 3.0 ports work exactly the same as the native W510 USB 3.0 ports: o the flash drive is mounted and accessable o I click on "remove the drive safely" and the USB 2.0 flash stick unmounts, but continues to flicker o I pull it out and plug it back in and NADA...the port seems to be dead. o I put the flash into the other USB 3.0 port and that one is alive, mounts the stick o I unmount it (it flickers), I pull it out and put it back again, and the port is "dead"....I move it back to the first port and that port is alive again So the Transcend USB 3.0 ExpressCard Adapter is having exactly the same characteristics as the built-in controller. The "dead/non-dead" is also exhibited with other devices, not just the flash. md -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
