USB-I2C interface not showing up in Bridge Control Panel

[MercurialMoon]

Hi,

I have a PSOC4000S kit, the CY8CKIT-145-40XX.

And have PSOC creator, programmer and bridge control panel installed on a Win7 x64 machine.

I downloaded the sample program, "Infineon-CY8CKIT-145_Code_Examples-Software-v01_00-EN"

and built and programmed the "CE210709_CapSense_Linear_Slider_and_Buttons" project into the kit with PSOC Creator and PSOC Programmer.

However I cannot connect to the Capsense Tuner via the EZI2C interface.

To debug it i fired up Bridge control panel and i can see only 2 entries meant for UART over there

COM3(This seems to be the kit) and COM1.

There is no entry for I2C  in the list, is there any special driver I need to install to get the USB-I2C bridge to function?

Hi @MercurialMoon 

Can you please let me know the following to help you better:

1] Are you able to observe the KitProg/<serial Number> option when you connect and disconnect the kit from your PC?

2] If no, then are you observing the same on both the Kits you have?

3] Can you let me know the version of PSoC Creator you have installed and the KitProg version that appears in the bridge control panel?

Warm Regards
Alen

Hello @AlenAn14 

1) Screen shot of Bridge control panel attached, it only shows COM3 port for the attached kit. I2C option not available.

2.  I have only 1 kit, CY8CKIT-145-40XX.

3. PSoc Creator version 4.4(4.4.0.80), kitprog version is not seen in Bridge control panel.

But i can see it in PSoC programmer.

Hi @MercurialMoon ,

Can you please update the KitProg firmware from the 'Utilities' tab in PSoC Programmer:

After the upgrade (to KitProg v2.21), try once again to see if you are able to see the KitProg option in Bridge Control panel.

Can also please let me know if you are observing the KitProg tag under 'Ports' and 'Universal Serial Bus Controllers' as shown below?

Warm Regards

@AlenAn14 

No significant change after doing a update  from the Utilities tab.

This is what i see in device manager

Hi @MercurialMoon ,

The 'KitProg3 Bridge' should appear under 'Universal Serial Bus Devices' instead of 'Other Devices' for it to be recognized in the bridge control panel as below:

In the device manager, can you right click on 'KitProg3 Bridge' and click on 'Properties' and then click on 'Update Driver' >> 'Browse my computer for drivers' >> 'Let me pick from a list of available drivers on my computer'. Here you will see the below:

Select 'WinUsb Device' and then click 'Next'.

Let me know if this works.

Warm Regards

I right clicked an the , Kitprog3 Bridge (with exclamation mark) and did update driver, the followed the instructions as you wrote in your reply, But there is no entry of "WinUSB Device" on my PC.

I also tried manually searching for winusb.inf and tried to select it as the driver but it doesn't work that way.

Hi @MercurialMoon ,

I believe this is mainly because you are using the Windows 7 OS as the following description from the Microsoft documentation mentions:

Before Windows 8, to load Winusb.sys as the function driver, you needed to provide a custom INF. The custom INF specifies the device-specific hardware ID and also includes sections from the in-box Winusb.inf. Those sections are required for instantiating the service, copying inbox binaries, and registering a device interface GUID that applications required to find the device and talk to it. For information about writing a custom INF, see WinUSB (Winusb.sys) Installation.

The steps I mentioned previously was basically from WinUSB (Winusb.sys) Installation. Try this out once more and if this does not help, then you will have to try the steps given here.

Also try creating a ticket at Microsoft for getting the 'WinUSB Device' entry in the 'Update Driver' section for Windows 7. They will be able to help better on this.

Warm Regards

Hi @AlenAn14 

In which .inf file do I need to make changes specific to Windows 7 OS as mentioned in your linked articles? Can you kindly let me know the location of the file?

Hello @AlenAn14

I found a solution and applied it, the USB-I2C bridge now shows up in Bridge control panel.

The solution is at the following link  https://community.silabs.com/s/article/manually-install-winusb-driver-on-windows-7?language=en_US

I am pasting the solution here in case the link breaks

Manually Install WinUsb Driver on Windows 7

Win7 ships with the correct 'winusb.sys' file, but is missing an updated '.inf' file that associates the driver with "usb\ms_comp_winusb" devices. Normally if the USB device supports Microsoft OS

Win7 ships with the correct 'winusb.sys' file, but is missing an updated '.inf' file that associates the driver with "usb\ms_comp_winusb" devices. Normally if the USB device supports Microsoft OS descriptors, then it will allow Windows to automatically install the WinUSB driver. This mechanism is supported "in-box" for Win8 and newer. For Win7 the mechanism is supported through Windows update. Depending on the update policy for the Win7 machine, the appropriate driver may or may not be already available on the machine. If it is not already on the machine, user can use the following manual procedure to install the driver if necessary.

1. Search for "windows phone winusb" at [Microsoft®Update Catalog|https://www.catalog.update.microsoft.com/Home.aspx].
2. Download "Windows Phone - Other hardware - WinUsb Device".
3. Extract the contents of the downloaded '.cab' file to a temporary folder.
4. In device manager select "Update driver software ..." --> "Browse my computer for driver software".

5. Navigate to the temporary folder with the downloaded driver and complete the installation.

This procedure only needs to be done once.
