Is there a way to coax a USB device interface on the EVM (TMDXEVM8168)? The chip supports host or device, but the connectors would not seem to accommodate.
I'm looking for *any* way to get a single device interface. Any ideas?

Hi,
The EVM has two functional *host* ports, accessible via "A" type connectors. I want the EVM to be a USB *device*, so it could (for instance) connect as a peripheral to the USB port on a PC.
The processor can do it, but I don't see how to access that functionality on the EVM.
There is a HW limitation wrt dynamically switching from Host to Device on the USB ports on EVM. The HW detection capability is not present and therefore you have to choose either HOST or DEVICE in SW. Let me know if this answers the question.
Thanks.

Release Notes : latest PSP that is part of EZSDK has "Concurrent usage of one port as USB host and other port as USB device (refer USB Userguide for details".

To make EVM as usb device mode (usb0 instance), please configure the kernel for USB-Device mode with CDC/RNDIS (as builtin) or File storage gadget as module and connect EVM to PC using A to A cable, You need load gadget module if it has built as module.
