hi everyone I am trying to connect to cp210x UHRT chip, but I con't configure the chip due to lack of the needed parameter like data a size. I already tried but it dosen't work without this parameters, is there is anyway to do it?

The controlTransferOut method accepts two parameters, a USBControlTransferParameters and a BufferSource. The USBControlTransferParameters is used for the setup packet that is transmitted to the device, and the length of the BufferSource is used to determine the size of the data. For reference, please look at the specification for controlTransferOut.
