Can you capture the USB trace with BUS HOUND? We need to know what happened when you connect FX3 to your PC.
I'm appreciate for your reply.
I check my firmware , I find that CyFxUSBManufactureDscr has a mistake
const uint8_t CyFxUSBManufactureDscr __attribute__ ((aligned (32))) =
0x09, /* Descriptor size */
CY_U3P_USB_STRING_DESCR, /* Device descriptor type */
CyFxUSBManufactureDscr has 10 bytes , but i set the first byte 0x09 . Then I set this to 0x0A.
W10 can identify it correct. But I have no idea why Win7 is correctly.
I'm trying to install driver now.
