USB superspeed peripherals Forum Discussions
Hello,
We want to certificate driver by resell process.
Could you please confirm below information?
publisher display name : Novitec
os : win 10 x64, win 10 x86, win 11
driver version : 1.2.3.20 (included in SDK v1.3.4)
chip : fx3
Thank you 🙂
Is there any simple standalone utility to download image file into the i2c EEPROM ?
our cameras based are based on the FX3 microcontroller.
Some cameras, after they are running for several hours, are not detected by windows on some USB ports (the device manager detects nothing)
- On the same computer, the same camera is detected on some USB ports, and not on other. when I connect the camera,
Another camera (same HW, same FW) is detected on this USB port.
I try to force Full speed mode, in this case the device manager detects the camera, but in Super Speed, the device manage doesn't detect it.
If I use a USB3 Hub or an USB analyser between the camera and the PC, the camera is detected again.
Do you know what happen and how to solve the issue/

Hi, I'm a software engineer using FX3/CX3 products and have some questions about I2C.
I referenced an75779 and cyfxusbi2cregmode for implementing application.
But there are difference between that examples and so I'm wondering why those example different.
In an75779, SensorI2CAccessDelay() function is used after CyU3PI2cTransmitBytes() function.
In SensorI2CAccessDelay() function, this is just loop I think.
But in cyfxusbi2cregmode example source code, CyU3PI2cWaitForAck() function is used after CyU3PI2cTransmitBytes().
What are different between those?
Show LessFX3 Serial number in Bootloader mode (j4 jumper insert - PMODE)
Hi,
I'm using multiple FX3 board devices and I connect them under 4 DS port HUB,
When I restart the computer all off them starting with Yellow Exclamation Mark Issue in Device Manager.
I think it's because when all of the FX3 in Bootloader mode then the Serial number is the same
Serial number "USB\VID_04B4&PID_00F3\0000000004BE"
Can I change the serial number of the Bootloader mode? I now how to change the descriptor serial number of the firmware that I'm burning to the device but I don’t know how to change the descriptor serial number when the device is in Bootloader mode.
I add picture so you can see the problem inside the device manager.
You can reproduce the problem at your end by:
- Connecting 4 FX3 with J4 jumper insert under HUB
- Restart the pc
- Enter to device manger to see if the device enumerate proper
Thanks,
EliW.

When I download CPLD_Programmer to a super speed explorer kit with the cpld accessory board attached, the fx3 does not enumerate - there are no entries in the USB Control Center making it impossible to configure the CPLD. The link to the example files for the SuperSpeed Design examples on the Infineon site take me to amazon to purchase the book (which I already have) so it is of no use. I found a copy of the files on the net. There is of course no guarantee the files have not been changed but they are all I have. Could you provide either a working link to the example files or the full source for CPLD_Programmer?
Show LessHi,
I downloaded the an65974 material and flashed the SF_loopback.img on the FX3 and everything's working. But if I import the SlaveFifoSync directory inside Ez USB suite tool (1.3.4) and I then compile, after having flashed the freshly generated .img image, the device interface is not even detected anymore by the Control Center. I also tried the compiling operation on a Linux machine (make command + elf2img tool), but I get the same problem: after having flashed the .img, not even libusb can list the device
Hello everyone,
I have an app that we wrote using an older version of the CyUSB library that I'm moving to the modern version in an effort to support a newer board that uses the FX3 instead of the SX2. One of the things the app does is when it's cleaning things up at the end is call the abort function to cancel any ongoing communications.
I've found that when we call that function now though, the function never returns, which locks up the app.
Do you have any idea why this might be happening, or what I could do to investigate further? Is there a trick that I should know about working with this object beyond what I've read in the programmer's reference?
Show LessHi all
I am working on CYUSB3KIT-003 kit with image sensor ov7675 currently, and using AMCap on PC
I follow the instruction AN75779, and made some modify with the previous discussion
Re: Cypress EZUSB FX3 to stream video from OV7670
AN75779 modification - FX3 for streaming image sensor data
Hardware setting:
ov7675 is initialized by another device, so i2c function on fx3 is disabled
only connect DQ[0-7] PCLK FV LV to fx3
since ov7675 default resolution is 640*480 so I connect the fx3 to usb 2.0 port on PC,
according to the AN75779, the uvc will switch to 640*480 automatically, and AMCap recognize this as well
I enable the #define DEBUG_PRINT_FRAME_COUNT to check the status of frame receiving
and using oscilloscope to check the FV and LV existing, and it does
but i can't see any image on AMCap
the debug info:
most of the time:
UVC: Completed 0 frames and 0 buffers
UVC: Completed 0 frames and 0 buffers
UVC: Completed 0 frames and 0 buffers
UVC: Completed 0 frames and 0 buffers
sometimes:

is anyone encounter the same problem?
Show Less下图start_time与end_time 是VS2013(上位机)中读取一次32768个32bit的时间,监测到上位机读取的数据速度在us级别;我用matlab和vs2013联合编程,matlab调用vs2013中生成的静态库,但是vs2013发送数据到matlab过程中速度变慢,为150ms左右,这是怎么回事呢请教一下。
