Using a Nano 18, Nano 18/28 Proto Board, and a USB2Serial adapter

PC is AMD A8-3850 CPU, 8 gb RAM, Windows 7 Home Premium 64 bit

I downloaded the communications driver and ran DPInst64.exe as Administrator. Received the unsigned driver warning, clicked install anyway. After several seconds, the same warning came again clicked install anyway, then nothing more happened.

Applied power to the board and connected to a working USB port on the PC. Windows msg. says failed to install driver. In device manager I see the device under USB controllers, but it has the yellow warning triangle with an ! in it.

I've uninstalled and reinstalled, same result.

Any help will be much appreciated.

TIA,

Further info:

AC adapter is 9.0 V - 0.66 A (came with my Arduino Diemilanove.

When I attached the Arduino to this computer for the first time, Windows automatically installed the driver, and the Arduino communicates over COM4. I can upload sketches from the Arduino IDE.

Perhaps the driver for the Basicmicro is trying to install to COM1 ? No new COM port appears in the device manager. Or maybe the Basicmicro driver works differently.

You might look at this posting:
atompro-f486/usb-drivers-not-working-windows-7-t9359.html

First look at the instructions given by Acidtech. But since then, the current USB driver has changed. There are links to newer ones farther down in that thread.

Thanks for the reply Kurt.

I got the latest driver as per the thread you referenced, but AcidTech's instructions fail because you cannot select the actual inf file, only the dir where it lives. Windows finds nothing there it likes. Others in the thread pointed this out also. Some provided some work workarounds, but I've spent enough hours on this already and don't wish to keep chasing solutions that may not work anyway.

This is a problem Basicmicro needs to fix. Windows 7 has been out long enough for them to have a proper driver. My Basicmicro goes in the drawer. If BM updates their driver for Windows 7, I'll try again, otherwise I'll write off the waste of $40.

You didn't follow the instructions.

9. Click "Let me pick from a list of device drivers on my computer".

You must click "Let me pick from a list of device...". If you instead click the browse button on that screen you will get to where you are getting to which is wrong.

As I said in the original post, you must follow the instructions exactly.

We don't have signed drivers. The drivers we have are valid just not signed. However on some 64bit installs Win7 decides they can not be installed. Only unsigned kernel mode drivers are supposed to require signing but apparently that isn't always the case. These are user mode drivers but Windows decides very randomly that they can or can't be installed. So we have this workaround.
