FT232H Module not detecting

<< < (2/2)

FTDI Community:
Hello,

Did you attempt to remove these components on a fresh board, or a board that was already presenting the issue?

Could you clarify the voltages for VCCD and VCCIO on a working and non working board?
Also please let me know if there are any signs of damage or burning on the IC once the issue appears.

Your schematic doesn't look to have any issues, but can you clarify if the FT232H is connected to a target when the issue occurs?

The lack of crystal oscillation indicates that the host machine has not enumerated the IC.
Please use our MicrosoftUSBView utility, and take a screenshot of the output for a device which is showing the issues.

Best Regards,
FTDI Community

Hello,

Thanks for your reply.

I have assembled another PCB and now it is working properly. May be it was USB port issue.

Thanks for all suggestions.

Hello,

Glad you have managed to get a board working now!
Please let us know if you have any further issues.

Hello.
In my case, my two laptops are detecting ft2232h as a ft4232h on both ft_prog and mprog >:(.
Why this happens? :-\

FTDI Community:
Hello Asrorr,

Are you using a custom hardware design or one of the FT2232H Mini Modules?

If you are using the mini module, please ensure you have powered the device in either configuration as per Section 3 of the datasheet (see the bottom of page 7). It is important that you make all of the connections denoted for either a Self or Bus powered configuration.

Best Regards,
