I bought a new FTDT232 from a local electronic shop and have been trying to install it to my laptop which uses windows 8.1 X64 (single language). Two red LEDs blink for four times when I connect it to the USB port but windows does not recognize the device. It’s a whole week I’ve wasted unable to update the drive. I have gone installing all drivers and updating via the windows device manager. Every time it say that “Windows has determined that the driver software for your device is up to date”. I’ve browsed the FTDI website and downloaded many drivers and have gone through the AN_234_FTDI_Drivers_Installation_Guide_for_Windows_8.
The drivers are as follows.
- CDM 2.08.24 WHQL Certified
- CDM v2.12.24 WHQL Certified
- CDM v2.12.28 WHQL Certified
But none of them works. But ends up with the same message.
I have already tried by restarting the computer holding the shift key – Startup Settings - Advanced options – Startup Settings – Troubleshoot – Startup Settings – Restart – Startup Settings – 7.)Disable drive signature enforcement & then updating the driver but it also didn’t work.
Can anybody help me to sort out this problem?
