Goodness knows. I have a USB-IDE enclosure that works okay when you turn on power to the drive before plugging in the USB cable but not vice versa. (Or maybe it's the other way around; I can never remember.) There's plenty of bad hardware out there, and not too much we can do about a lot of it. If you're really curious and want to get more information, you can turn on CONFIG_USB_DEBUG and CONFIG_USB_STORAGE_DEBUG. Then see what shows up in the dmesg log when you plug in the drive.
