Hi Albert,

In your usb_drv_cdc_class.jal you ave following code:

------------------------------------------------
if false then

                        usb_control_mode = USB_CM_CTRL_READ_DATA_STAGE_CLASS

                        //--  need to prime ep0 IN with some funky data here
                        usb_send_data( 0, cdc_line_coding, 7, 1 )

else
                                usb_delivery_bytes_max_send = 0xFF
                                usb_delivery_bytes_to_send = 7
                                _usb_copy_array_to_ram( 
USB_IN_DELIVERY_BUFFER_LOC,
cdc_line_coding, usb_delivery_bytes_to_send )
                                usb_delivery_buffer_size = USB_EP0_IN_SIZE
                                //-- usb_delivery_bytes_to_send
                                usb_control_mode = USB_CM_CTRL_READ_DATA_STAGE
                                usb_delivery_bytes_sent = 0
                                var bit dts_bit at usb_bd0in_stat : 
USB_BDSTATUS_DTS
                                dts_bit = low

                                //-- AF ISO OF PRIME
                                usb_send_data_chunk()
end if
--------------------------------------------

What kind of construction is? When is evaluated that if? What is
querying?

"if false then" - what evaluate this "if"?

Thank you in advance!
