Hi everyone, (please Cc) I am currently running 3.8.0-rc4 and see the following behaviour: When I plug/eject my kindle a few times, suddenly the kernel does not see any USB activity any more. Nothing. PLugging in the kindle - no reaction, plugging in a usb kbd - no reaction, plugging in a usb mouse - no reaction. All dead. I turned on udev debug mode, no messages at all. I restarted udev - no changes. Unfortunately I have build the kernel with USB fix built in, so I cannot unload the module. While everything connected, a simple lsusb didn't show up any devices but what was there from the beginning. Bu then, I did a lsusb -v and whoops everything was back there ... Is there a different way to achieve this? Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 002: ID 8087:0020 Intel Corp.
