John, you won't necessarily get the yellow triangle of death as the driver may be compatible with the cable but not with Chirp.

In the case of a counterfeit Prolific 2303, you might get a yellow  triangle, I don't know because I don't have a counterfeit.

In any case the recommended Win7 driver build is 3.2.0.0.  That's what I use and have zero problems.

One thing from Windows 7 is it will visit the Microsoft driver cloud and look for a newer version even if you disable automatic updates.   Best thing is to retrofit the 3.2.0.0 drive while disconnected from the  internet. And tell the driver installer where to find the driver files.

And keep the cable plugged in by all means to the same port. Each time you move the cable to a different USB port Windows will reassign a COM ports and probably try to update the driver.

Milton.

Russ, There is nothing wrong with the version of CHIRP you are running.   When you say the driver is Up-to-Date, you have described the issue. As mentioned, you need to Back Date your driver to Prolific 3.2.0.0 The driver and an short explanation as to why can be found at http://www.miklor.com/COM/UV_Drivers.php   In device manager, if there is a yellow warning triangle under 'Ports' or 'Other Devices', you have an incompatible driver.   Please report back and let us know the result.   John K3NXU http://www.miklor.com     From:chirp_users-bounces@intrepid.danplanet.com [mailto:chirp_users-bounces@intrepid.danplanet.com] On Behalf Of Milton Hywatt Sent: Sunday, September 29, 2013 2:44 PM To: russell meredith; Discussion of CHIRP Subject: Re: [chirp_users] help   The latest driver that will work with Baofeng is 3.2.0.0 for Windows 7.  Go here and read the facts about your radio and cable. It will probably get you sorted out: http://www.miklor.com/uv5r/

I would agree with this if you were talking out the Baofeng software. But not when talking about CHIRP.

I have tried nearly every Prolific driver I could get my hands on to determine the latest driver that would work with the unauthorized USB-to-Serial chip copies that are normally used in low cost programming cables. The latest driver that you can use is v3.3.2.105. CHIRP works fine with this driver. The older Baofeng software from a year ago (I haven't tried the latest Baofeng software) won't work with it. I had to downgrade to v3.2.0.0 before the Baofeng software would work. This is the sole reason that I recommend this driver for cables with unauthorized chips.

I have no doubt that CHIRP will work on any programming cable (Prolific, FTDI, CP2102, etc.) that provides a working virtual COM port.
