Comment 12 for bug 182931

It is would also be helpful to have the dmesg output relating to the USB sticks insertion. Insert the stick and you should see something similar to the following in the output of the dmesg command:

    [102386.120296] usb 5-1: new high speed USB device using ehci_hcd and address 5
    [102386.255443] usb 5-1: configuration #1 chosen from 1 choice
    [102386.257622] scsi9 : SCSI emulation for USB Mass Storage devices
    [102386.264768] usb-storage: device found at 5
    [102386.264779] usb-storage: waiting for device to settle before scanning
    [102391.264352] usb-storage: device scan complete

This has information on how fast the USB connection is to the device. If you could paste that into this bug.
