I successfully installed Arduino SW and developed sketches which I was able to load and execute early this year. I'm using an Arduino Nano v3.0. Now I'm unable to communicate with the Nano. When I connect it, it tries to load the driver(s) but I get an error window saying 'Device driver software was not successfully installed'. Device Manager shows the FT232R USB UART device under the heading of Other Devices but the properties for this device says the drivers aren't installed. When I try to update the driver I get a message saying that Windows can't find the driver for this device. I've downloaded the latest VCP drivers from FTDI to no avail.
I've even tried loading older drivers. When I run the FTDI executable installation file it runs and I get two green check marks and a 'Ready to use' status but still nothing works and the Hardware Manager still says that the drivers are not installed (Code 28).
The only thing that I know of that's changed since I was successful early this year are the numerous Win 7 upgrades. Any suggestion on a solution would be greatly appreciated.
Crossroads,You may be missing the point, we had units working and today when we plugged them in they no longer work.The problem is related to the version of the board. In other words I have 4 boards here right now. 3 work fine and the other will not be assigned a com port. A partner has a bunch of the same units I have problems with and all his stopped working today also. Oct 1 is a bad day for many Nano's.Did Microsoft do a update?
Did the driver have a time bomb in it. No one seems to know yet.If I miss understood and you had a unit fail and you went to a new driver let us know.Highflier.
I don't know what's going on with others. Just tried mine again (1.0.6 on Win7Pro), IDE had been open for a couple of days so I get a build folder disappeared error. Restarted the IDE, opened Blink and it downloaded fine again.My Sony Vaio with WinVista that I used for nearly 4 years (and still use occasionally because it has many sketches on it and sometimes I have eagle routing going on in one room while I code in another where the hardware is, but less and less as the keyboard is getting fiddly) still runs file also.I am stumped as to others have such difficulty.I let both computers do Windows updates automatically.
Maybe that has something to do with it? I believe this is FTDI version 2.12.00, release note here I guess if there was a change to nobble fakes they might not publish that info.That update is pending in my Windows update.Possibly due to recent news about USB hacking vulnerability they have been tightening up on USB drivers, or someone just goofed an update.FDTI have a tool to edit the data in their devices called FTPROG, it might be a way to recover faulty devices. It's also a way to mess it up completely, but if it doesn't work anyway maybe no loss.
