(Sorry for starting so many topics today, but they're all on different topics.)
I have a Saber that, when read in RSS, comes up with the "Serial Bus I/O error." (I swapped out some modules inside, and then tried to read this radio for the first time in RSS, so I'm not sure if I broke it or if it was already that way.)
Programming setup is fine, as I can read/write to another (identical--serial numbers are sequential, even) Saber without trouble. I also tried moving the 'guts' between the two cases, and it followed the radio, not the case. (Meaning that the ribbon inside the case is not the culprit.)
I did put the old modules back in, and inspect everything for a proper connection, but I'm not sure what else I should be looking for. The radio operates fine, it's just incapable of being read by RSS. Pointers, anyone?

I am curious as to the version you are using to read these radios.
Most Saber RSS will read just about all models, and all version platforms as well, so something is amiss here.
If all the modules can be read and programmed to while in different chassis, then I would suspect a main board problem to be the likely culprit here.
IF you can check the crystals on the board as well as the reference oscillator to be certain they are all operating, then again, suspect the main board.
Check for bent pins after you swap modules back and forth, unless you are absoluteley positive they are all straight, and since they all function as stated previously by you...you have a defective board, OR at the very least, a bad trace or two that is preventing programming or reading.
You can expand the lower frame spring contacts on the radio, they get compressed after several years in the case and can become intermittent as well.
Gently lift upwards on each row of contacts to make sure they appear a 'little' higher than first seen, and then do the same to the second row.
Check the case contacts at the bottom to make sure no oxidation is present and they are all gold in color and shiny as well.
Another place to check is the battery contacts, later versions had a 'plate' under the contacts to maintain pressure, earlier versions did not have this, so you had to periodically adjust the height of these so that constant firm pressure is applied to the battery.
