Yes, it is exactly the same every time Yes, every computer (for several kernel versions now) Yes, it works in Windows straight away (without doing any tricks) One thing I have not tried yet is to set delay_use option of usb-storage to a higher value. Maybe the device is still starting up and kernel tries to initialize it too quickly. I have usb-storage compiled into kernel now, instead of as a module, so I need to remember to change that that next time I plan to reboot.
