The overall situation is very confusing. Quite apart from any possible bugs in the iPod firmware, we have the fact that at least two different drivers are involved (ub and usb-storage) and that the "eject" application itself wasn't (and presumably still isn't) entirely complete: In the cdrom part of the program, it would try various combinations of an "Eject" SG_IOCTL, a START-STOP command, and/or a PREVENT-ALLOW command -- but then once it had gotten the device into a state where it would be willing to eject, the program didn't issue another "Eject" ioctl! It wouldn't be surprising to see a similar mistake in the direct-access portion. Alan Stern ------------------------------------------------------------------------- Take Surveys. Earn Cash.
