There is no free Linux driver for it. The Linux driver from the offical TransDimension costs a lot of money. Actually, I want to develop the driver for the Chip, but as little development material, the job will cost my lots of time. So I want to know something about the driver development of the USB Host Controlers esperially the OTG Controlers. Could you give me some hints? Thanks a lot Best Regards.
