Answer:
NOTE: WUSB-NL DVK is intended for use with the WUSB-NL modules supplied with the kit. In case you need to use this kit with any other WUSB-NL based device, the WUSB-NL module needs to be modified. Follow the instructions provided in this article to modify the module.
CAUTION
INSTRUCTIONS TO MODIFY WUSB-NL MODULES
Perform the following changes on both the WUSB-NL modules:
Figure 1 WUSB-NL Module and Location of C7 and C8
Cypress recommends the following parts from Murata for this purpose:
After the changes are completed, the WUSB-NL modules are ready to inter-operate with any non-DVK hardware.
INTEROPERATING WITH NON-DVK WUSB-NL HARDWARE
In order for a modified WUSB-NL module to inter-operate with a non-DVK hardware, the firmware running on both the hardware’s needs to be compatible. For this reason you must port the WUSB-NL driver provided with CY3668 to the non-DVK hardware before initiating data communication between them. If your application requires AgileHID protocol, you must port the AgileHID protocol provided with CY3668 DVK to the non-DVK hardware as well. Alternately, you can port the firmware (WUSB-NL driver and AgileHID protocol) running on the non-DVK hardware to CY3668 DVK as well.
