I don't know the peripheral, but on ethernet both ByteCount above 1522
and CRCError can be a collision or interference, and device reset in
response seems a bit eager.

CRCError can also be a fault in a sending device.

I remember having to split networks with hubs or switches to keep
numbers down to what the customer wanted.

Suggests it isn't CRCError or large packets.  I'd expect an ethernet
peripheral to keep going quite cheerfully after either of these
events, without anything additional other than what is normally done
to prepare the peripheral for the next transfer.
