FT600q config problem

(1/1)

Zoltan:
Hi!

FT600q.
By accident, during configuration, the Manufacturer, Description, Serial (via API function) fields were incorrectly set! From then on, the IC is not available, even the driver indicates an error (STATUS_DEVICE_DATA_ERROR)!

The factory configuration program can't open it either, so I can't rewrite these fields either.
How can I get it to work again?

Thanks,
Zoltan

Hello,

I wonder if you also changed the VID and PID?

Please check the device details with USBView Utility:

https://ftdichip.com/utilities/#microsoft-usbview

Does the device appear in Device Manager if you are using Windows?

If the VID/PID is changed then it might explain if the device can't been seen.

If that's the case then you can try editing the D3xx Driver files to include changed VID/PID numbers.
Note that this breaks driver signing so you may need to install via disabling driver signature enforcement or using test mode. Both are detailed in this external link:

Then hopefully you can use the configuration tool to change back to defaults:

Hello!

Yes, it is visible in the device manager, but its name has an exclamation point.
VID, PID have not changed! As I can see, the other parameters have not changed either!
Only the text fields (and the length and type fields) were incorrectly overwritten.

I see error code 10 in the driver information tab. STATUS_DEVICE_DATA_ERROR
With the explanation "The device cannot be started"...

I think that because the device cannot be started for some reason, it is not available for the Configuration program either.
The question is, why doesn't the device driver start when it finds incorrect "Manufacturer, Description, Serial" fields?!
And is there any way to start the IC with basic config data, without reconfiguring the IC?!

Thanks,
Zoltan
