Description of the problem/feature request/other

Issue encountered on Matrix, here.

Encountering this error when going into PRE-OP:

Invalid SDO response. Type: Coe (expected Coe), counter 1 (expected 2)

Also mentioned:

So it looks like it‘s always the first slave behind this card here that‘s affected of the „invalid SDO“ bug.

First, the slave behind ek1100 always fails :) you can clip different slaves in this ek1100 and no matter which I put in there, the first slave behind it that’s not within the ek 1100 causes the error

Example:

Device 1006 would always be the one to fail. It seems to be position-related, not device-related.
