OTG specification requires that kernel drivers communicate events to the "Application Layer". However, Linux kernel 2.6.10 offered with DM6446 DVSDK lacks the communication infrastructure to make this possible.
Juan,
You have listed the limitation on LSP1.2 platform for DM355 and DM644x devices. But if you have your own OS stack and related applications then there would not be any restriction on being compliant with OTG standard.

swami, you are correct; I should have added a sentence to highlight this is a software limitation due to 2.6.10 kernel as opposed to a hardware limitation.
