OK, so that sounds as if removing the USB device before   vgchange -an
will not affect the device but only the host PC.

And my own experience suggests that the same is true if the
unlocked device is removed before locking it.

It's not that I don't perform the correct sequence of steps,
but just that accidents happen and I like to be prepared for
the consequences. The effects of removing a device without
unmounting it are well documented and have been for years.
OTOH I have found a deafening silence about the effects of
not locking an encrypted device.

Glad to help.
