Hi,

You can use the QUsbEndpoint::makeControlPacket method to generate control packets, then write it just like a normal endpoint.
It mostly depends on the device.

m_read_ep = new QUsbEndpoint(m_usb_dev,QUsbEndpoint::controlEndpoint,0);
m_read_ep->makeControlPacket(buffer,QUsbEndpoint::recipientInterface,QUsbEndpoint::requestClearFeature,0x0603, 0x0600, 0x3E00);
m_read_ep->write(buffer);

Should I write like this?

Then where do I receive and return the data?
