TI-RTOS-MCU: Technical query regarding USB

Part Number: TI-RTOS-MCU

Hi Experts,

Our customer have been using TIRTOS TIVA C 2.16 library,From this USB library. They are configuring the USB to RUN as a CDC device,They  see that there is not option to provide END point size for In and out end points,But when they capture the endpoint details . it shows as 64 bytes。Now they use the USBBufferWrite() from the library to send data,Will the function support bytes greater that 64?They want to have a transfer size of 256 bytes.

If the USBBufferWrite() supports transfers greater than 64. Then what is the maximum transfer size supported by the function? Does it do internal buffering?

Please advise. Thank you.

Best regards,
Gerald
