It's not just the ordering of readers that is the issue. I ran across
this problem just now:

https://paulphilippov.com/articles/how-to-fix-device-not-accepting-address-error

... so plugged the ACS reader into a docking station port, thinking it
would be able to supply more power. The ACS reader started working
again, but even though it is still the first reader in the list, gpg2
can't talk to it:

dmesg output:

Unfortunately it seems that since kernel 2.6.38 there is no longer a
reliable way to cut power to an internal USB device, so I can now only
use my PGP card with a 50% success rate on this machine - short of
cracking open the case and disconnecting the internal broadcom reader.

This basically screws my intended use of this PGP card.
