So far I've opened only a couple of genesys scanners, but out of those that I did open, the chip was clearly marked with its genesys chip number, e.g. GL843. I think it's very likely that 5200F has proprietary controller, because there are few reasons why chip manufacturer would relabel its product just for a single customer. Regards, Povilas
