Hi,

   

Does the CYUSB3014-BZXC IC support USB3.1 Gen1 standard? We have tried the sample code, Cyfxisosrcsink, and works with USBbcd 3.0. However, we changed the USBbcd to 3.1, but it doesn't work(streamer can't receive data from device anymore), Do Cypress have any suggestion?

   

Thanks.

Yes, CYUSB3014-BZXC IC supports USB3.1 Gen1 (5 Gbps) standard as said in the FX3 data sheet.

   

I tried changing the bcdUSB to 3.1 in the Cyfxisosrcsink example firmware. It is streaming successfully as shown in the below figure.

   

Did you change any other along with bcdUSB to 3.1?

   

I couldn't attach Cyfxisosrcsink project file (changed the only bcdUSB to 3.1) due to some technical issue.

   

I will try to upload it later.

Hi srdr,

   

We have test your upload code on CYUSB3KIT-003 explorer kit, but it still fail.

Hi srdr,

   

I have tested the device at win 8 and it shows "not enough USB controller resources", Probably host driver issues, do you have any suggestion?

Hello Spark,

   

I tested the above-attached USBIsoSourceSink firmware with Win 7 and Win 10 OS PC's, unfortunately, I couldn't test with Win 8 PC. I can see device enumerated well and streamer app is streaming well on both Win 7 and 10. 

   

Can you do the following test and share the screen shot of it.

   

After loading the attached firmware to CYUSB3KIT-003, select the device in Control Center and then click on  Descriptor info in the Control Center and share the screenshot of it.

   

Can you share the firmware that you used for testing? I will test here for confirmation.

Hi srdr,

   

The attachment is the test result at win7. I just download the firmware code you uploaded without any change.

I tried with the attached BulkSrcSink_1 and can see streamer is streaming at low speed. This issue has fixed in the latest drivers, i.e provided with Type C PD Analyzer here http://www.cypress.com/documentation/development-kitsboards/cy4500-ez-pd-protocol-analyzer This is 1.2.3.17 version. Download this application and bind FX3 to this and check with the streamer. Do restart if required. And one small correction in the example firmware, the bcdUSB should be 0x10, 0x03 instead of 0x01, 0x03 which is shown below.

   

const uint8_t CyFxUSB30DeviceDscr[] __attribute__ ((aligned (32))) = { 0x12, /* Descriptor size */

   

CY_U3P_USB_DEVICE_DESCR, /* Device descriptor type */

   

0x10,0x03, /* USB 3.0 */ 0x00, /* Device class */

   

0x00, /* Device sub-class */

   

0x00, /* Device protocol */

   

0x09, /* Maxpacket size for EP0 : 2^9 */

   

0xB4,0x04, /* Vendor ID */

   

0xF0,0x00, /* Product ID */

   

0x00,0x00, /* Device release number */

   

0x01, /* Manufacture string index */

   

0x02, /* Product string index */

   

0x00, /* Serial number string index */

   

0x01 /* Number of configurations */ };

Hi srdr,

   

I find the message, "not enough usb controller resources" at win8 that is caused by the not enough host control endpoint. I removed the pieces of code in the configuration descriptor

   

    0x09,                           /* Descriptor size */
    CY_U3P_USB_INTRFC_DESCR,        /* Interface Descriptor type */
    0x00,                           /* Interface number */
    0x00,                           /* Alternate setting number */
    0x00,                           /* Number of end points */
    0xFF,                           /* Interface class */
    0x00,                           /* Interface sub class */
    0x00,                           /* Interface protocol code */
    0x00,                           /* Interface descriptor string index */

   

then it can receive data from device. However the USBCV test will fail at TD9.4, the information is shown below :

Do you have any suggesion?

It seems that there is an issue with USB Host controllers. Please test on a PC consists of different host controller without modifying the descriptors.
