    Is it OK to use CYUSB3KIT-003 as self-powered


      In CYUSB3KIT-003 the VBUS pin of FX3 is connected to the output of U11.


      Then when J3 is removed and VBUS pin of FX3 will depends on external power state instead of VBUS from USB connector.


      Will this have problem when the host PC change power states and can the firmware be modifired to deal with this problem?
