Partly hardware fault, partly driver fault.
-Hardware: one should expect that the transceiver answers only on one
address. However, many recent cards answer on 2 addresses.
-Driver: the docs specify that for recent cards (like yours) there is
always a transceiver at address 24. As the driver can only handle one
transceiver, it would be logical to first test for address 24 then test
all the others. Recent drivers (IIRC, from 2.2.19) do this, however, yours
(from 2.2.16) doesn't - it just goes from 0 upwards.
