I think it goes something along the lines of.
Elbox made USB drivers for the Spider card which work with the Poseidon USB stack. Chris Hodges confirmed the existance of malicious code in the Elbox driver, which some other guy found by reverse engineering the device.
According to Elbox this code would only become active if the drivers were hacked and pirated.
A big argument ensued and Chris Hodges decided to limit his potential customer base by cutting Elbox users out of the deal.
Now Elbox have allegedly decided to help Chris in his mission not to make money from Poseidon by stopping other people's USB hardware working when the have Elbox's drivers on their system.
