I don't think there's anything you can do. That's how the kernel does things (detach usb, reattach). We could: 1. postpone the device detach until after resume, and then only detach devices which are actually missing. I'm not sure how much madness this would involve. 2. postpone forced filesystem unmount until after resume to see if the disk comes back. I'm fairly certain this will involve a lot of madness.
