Hello All, I'm pretty new to USB and trying to develop a CDCEther driver for an USB Device. To start it I had some queries which I taught to clarify it before proceeding,
1. CDCEther doesn't requires an interrupt endpoint and doesn't uses it even if one is present in the device. So how does the host identifies that the device has data to be transmitted to host ?? Does host periodically send DATA IN request to the device ? If so what is the polling interval and is it configurable ? 2. What is the maximum Mbps/Kbps one might expect from CDCEther(Linux Host, kernel 2.4.18-14, USB 1.0) Does this throughput depend on the direction (Host to device, device to Host). I would expect Host to Device data transfer to be faster than device to Host data transfer.
