Mine is an 8700c, but I'm pretty sure the 'c' just indicates vendor
branding.

Aha, it seems that the command that was sent to the blackberry by your
version of the driver stays in effect for a while even after the cable
is disconnected.  When I first reverted back to the OpenBSD driver, it
used 100mA with config 0 and 500mA with config 1.  Now that I've power
cycled the blackberry, it uses 100mA on both configs.

Yes, I suspect that the 8700 unconditionally detaches after receiving
the command to enable 500mA charging, so I was getting into a loop when
it reattached and the command was sent again.  I think what needs to be
done is detect the power setting on the bus and avoid sending the
command again if it's already 500mA.
