problem in the communication between CY7C68013A USB programmer and ADAU1701 via PC with sigmastudio

hi.

i'm asking an help to solve my problem in the subject:

i have realized the programmable DSP for caraudio use with this components (see the scheme below):

- SURE ADAU1701 Kernel board

- CY7C68013A USB to program the EEPROM of the ADAU1701.

i'm setting the correct driver into the PC to see the CY controller as "analog device programmed" USB peripherical.

if i'm opening the file of my project in sigmastudio tool into the PC and click to "hardware configuration" sheet, is shown the USB connection as an ORANGE and not a GREEN block.

this means that there is not communication with the USB port in sigmastudio, while the CY programmer is seen correctly as "controller USB peripherical" in Windows manage device.

i haven't Always this problem; sometimes the connection was GREEN, but in the last months all my tries have had the same results.

it seems as the correct USB connection to the CY programmer is random.

is possible that when i try to reconnect, the CY programmer back to a previous state ? there are some setting to modify in order to see Always the correct comunication ?

do you have already faced this type of problem ?

thanks for your help.
