I think I've tried every solution I've been able to find in the forum
- got an earlier version of the drivers (2.10.00) and auto-installed
- did the manual install
- used FTDI's CDM removal tool and then manually installed again
- used MPROG 3.5, but it doesn't see the Nano even though there is an FTDI (with exclamation point) listed under "other devices"
- attempted another manual install of 2.10.00 (64 bit), but now, after getting through the first step and seeing the "usb serial port (with exclamation point)," updating the driver manually gives me the blue screen of death (twice)
The code on this particular Nano's FTDI chip is 1403 (I've seen the post that says 1408 is the real chip). My symptom is, I plug in a Nano, the drivers load (eventually) and I program it. I need t make a change, but the next time I plug it in to the laptop, no drivers can be found. I assume that what happens is, the drivers load the first time, see the fake FTDI chip, write 0000 to the EPROM, but since the drivers are loaded it works. But when it is plugged in the second time, the drivers see the 0000 and won't load.
Can anyone help me get MPROG 3.5 to see the Nano and undo the soft brick? Is there another way to get the ID fixed?
If you want an idea of how miffed I am about this, if I don't get a satisfactory program in a Nano, I don't have a heater control and it's going to be 14 degrees F tonight. Maybe I can get a scumbag from FTDI to spend the night turning the heat on and off.
