FT9xx Driver problem Windows 7
« on: April 24, 2020, 08:42:47 PM »

Hello, I'm developing a device with FT930 chip, and run into some driver issues.
My OS is windows 7 64bit, I have downloaded a CDM21228 driver setup file, installed the drivers, but windows can't find any drivers for it automatically.

I tried to install drivers manually, using "CDM v2.12.28 WHQL Certified" files, but
my device PID is not listed in the ftdibus.inf and ftdiport.inf files, so I changed them to match, could you please check these files?(added in the attachment) Maybe I did something wrong.
When I try to install the driver using these files the process begins but it ends with timeout error.

Also, if I change  ftdibus.inf and ftdiport.inf files, the driver signature is not valid, how this issue can be addressed?

I attached a screenshot from usbview program, and a device id from windows device manager.

Thank you.

Hello,

Which hardware are you using? Is it our FT9xx Modules or your own custom hardware?

The problem seems to be with the DFU drivers.
USB DFU programming can be a good option for production or field programming but not for development. The UMFTPD2A is recommended for programming and debugging.
The FT9xx modules and ICs in stock may be programmed with an old version of the bootloader so the DFU driver is not loaded automatically. An unknown device is shown in device manager. The FT9xx Programming Utility is also unable to see this device.
The latest DFU driver is now a WinUSB driver and should be installed automatically via Windows update.
Note that this is a USB DFU class device so can't be included in CDM v2.12.28 WHQL Certified as this driver is for our vendor class devices.
The FT9xx Programming Utility can be used to 'Restore Bootloader' to this latest DFU version but this requires the UMFTPD2A.

Please use the UMFTPD2A to ‘Restore Bootloder’ on the FT930 using the FT9xx Programming Utility:

It seems like the issue is in windows 7 updates, because it searches for a driver with high RAM (goes to 95%) and CPU usage,
probably KB3102810 update is needed, I will make an update if that solves the problem.

I'm using a custom hardware, also I have purchased a UMFTPD2A programmer and was able to program and run the SD card to USB converter example without any issues.

Hello,

Yes Windows Update will be searched for the driver which can cause delays.

However please ‘restore the bootloader’ using the UMFTPD2A which should resolve the issue.

Ive heard of needing raid drivers but never ahci drivers for windows, its usually a setting in your bios under Sata controllers.
Is it a fresh installation of windows 10?
