Forcing GEOM to re-taste a device

I am having trouble with a USB stick (a Verbatim store'n'go, 4 GB). It seems 
there is a timing problem. On insertion there are complaints that there is no 
medium present when attempting to discover the size of the device. It goes on 
to retry but eventually bails out.

However sometimes (only once so far) it manages to successfully retry and 
discover slices; presumably due to timing.

So I would like to force GEOM to re-taste the media ("camcontrol rescand da0" 
is not enough). Is there a way to do this?

And further, I was hoping to boot off of this. If anyone have suggestions as 
to how to make the retries continue for a longer period (other than patching 
the source), it would be welcome, since during boot I need the kernel to be 
able to taste it on the initial attempt, since failure will cause a panic 
immediately.
