I face the two problems when FX3 enurmation as a composite device.
1. I make FX3 to a composite device.(One is HID, another is Cypress FX3 USB StreamExample device) and then use Stream tool to do ISOC3.0 speed test. It have a probability to come out error message 0xC000000E during data transmission. The error would not come out when FX3 enurmation as a single Cypress FX3 USB StreamExample device.
2. When I switch the composite to USB2.0 device and install the Cypress FX3 USB StreamExample device driver on the NB. When I send the data through the HID devcie, there is a chance that an error code 29 CY_U3P_ERROR_MUTEX_FAILURE appear after CyU3PDmaChannelGetBuffer. If I uninstall the Cypress FX3 USB StreamExample device driver, I could send the data through HID without error.
The attach is cyfxisodscr.txt could anyone help me to solve the promblem? Thanks!!

Hi,
In addition to the descriptor file, we also need the main firmware C file to analyse the firmware. Can you please attach the same here?
