John (and everyone else) please **STOP** with the un-installing and re-installing.
That ended as a solution to problems long before Windows 98 came out. Re-installing is generally a colossal waste of time and rarely solves anything. What to do instead? Look in control panel and see what Windows tells you that your USB adapter is. If you purchased it from Elecraft, it will either be a Prolific unit or an FTDI unit. If it is Prolific, go here and download the correct driver: http://www.prolific.com.tw/eng/downloads.asp?ID=31 If it is an FTDI, go here and download the correct driver: http://www.ftdichip.com/Drivers/VCP.htm Disconnect your USB cable from the computer, install the correct driver and after the driver installs, then plug in the cable. After you plug in the cable, go back into Control Panel and see what com port # Windows has assigned to your adapter. Set your software to match that com port number. 73, Bob W5OV -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of John K3TN Sent: Friday, February 04, 2011 5:50 AM To: elecraft@mailman.qth.net Subject: [Elecraft] K3: Windows 7 and USB/serial redux I built a new Windows 7 64 bit Pro PC, got all my ham software up and running and for a brief period of time life was good. A bad RAM module brought that to a crashing (literally) end. Trying to recover from that I've been having a series of problems that keep pointing to what looks like the well known USB/serial port driver kind of problem. So, it looks like I'm going to do a complete clean re-install of Windows and start again. When I bought the K3 in Jan 2010 I bought the generic USB/serial interface from Elecraft. I had loaded the drivers pointed to from the Elecraft site - is that the safe thing to use? Somewhere else I saw some pointing to other drivers. I'm not going to even try to install any of these drivers until I'm 100% sure the Windows 7 setup is 100% stable, but at some point I'm going to want to update the K3 firmware... 73 John K3TN -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Windows-7-and-USB-serial-redux-tp599 2292p5992292.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
