Testing with Intrepid 8.10 alpha5. lsusb does not generates the oops anymore but it seems to stall forever.
Here is the relevant dmesg output (during lsusb a lot of these messages are generated, it must be stalled in some kind of loop): [ 299.312189] usb 7-2: new high speed USB device using ehci_hcd and address 3 [ 299.449215] usb 7-2: configuration #1 chosen from 1 choice [ 299.648638] usbcore: registered new interface driver libusual [ 299.744754] Initializing USB Mass Storage driver...
