Does Windows make the dah, dah, dah system noise when you plug the USB in?
If not try plugging the hardware in to another PC (with 12v PSU connected to MiniTiouner but no s/w installed) and see if you get the noise - if not you have a hardware problem.
You can program the module in the standard hardware - you do not have to remove it.

The module does not work with another PC and when I connect the USB cable I do not receive the noise from the PC that indicates that it has detected hardware. I also changed the usb cable, to no avail. I carried out the voltage measurements at pins CN2.1 / CN2.3 / CN2.5, CN2-11 / CN2-21, CN3-12 / CN3-22 but I find about 1.5 volts instead of 3.3, volts. I deduce that this is the stabilizer stage inside the module. I think I need to replace the ft2232h module because it's damaged. the 5 volt voltage that takes from the pc usb to the CN3-1 / CN3.3 pins is stable at about 5 volts. what do you think ? 73 de Vincenzo IW2HXW
the voltages on the base module are all regular, including the 3.3-volt one. , while the 3.3 volt voltage output from the USB module is not as regular as I said above. I don't want any electrostatic discharge to have damaged the USB module and so I don't think it can be replaced under warranty. I received the form in early August and it worked out regularly for a week. I plan to order a new programmed USB module. I hope that with the new module it works.73 de Vincenzo
I did these tests:
- I disconnected the ft22332h module from the pcb and connected the CN3 1 E 3 pins to power the usb at 5 volts.
- I connected the USB cable and this time the PC recognized me the device.
- I started the FT-Prog software and it recognizes the device but from an error in recognizing the eeprom (no eeprom detect blank device).
- I tried to reprogram the module but from an error.
I think it's the damaged eeprom. What do you think?
