I've just built up a new computer, using WIN7 for the OS [my XP machine crashed big time].

My trusty ol' STK500 worked great with the XP machine, interfaced with a USB-RS232 converter cable.
Using the same cable, I couldn't get Studio4 to "see" the board. I couldn't find the driver that came with that cable, so I bought a new converter cable, and freshly installed Studio4.18SP3, and the driver that came with the cable.
Same problem, no connection. I have 3 500s, and none of them are seen by Studio. There doesn't seem to be any troubleshooting means, just "no connection," so I'm flying blind. I have no idea what the problem is.

Can anyone suggest a magic bullet that will get my WIN7 box to fall in love with my ol 500?

When you plug the cable into USB, does Windows recognize it? After you plug the cable, do you see a COM port under Device Manager->Ports?

In Device Manager, yes, I see a COM1.
however, when I plug in the cable, I get a "new hardware" box, then it searches for the driver. The disc that came with the cable is in my optical drive, but the "earch" ends up saying "no driver found."
Seems mutually exclusive to me - I have a COM port, but can't find the driver for it.

I stuck an ATMega 16 in my STK500 and made sure my desktop (XP) could see it and read the signature. I'm using a (very cheap) USB/232 cable for the first time in my life since my old trusty box died a few weeks ago.

Then I got my laptop (Win7) and fired it up. I plugged in the cable and Win7 pranced around for awhile, then announced it couldn't find a driver. I tried to manually load it (from the internet), but no luck. I went to the manufacturer's website and downloaded the driver, installed it, rebooted, and all is now well. The cable is seen, the STK500 is seen, and I can read the signature.

Originally I thought I would have a problem since the cable configured as COM7 and my version of Studio only lists COM1-4, but "Auto" found COM7 without any hitch.

So thanks for the incentive to get the STK500 working on the laptop. I had been meaning to do that for several weeks now, but didn't have a round tuit. Good luck with your situation.

HI Chuck.
You say "manufactures" webiste. What MFG? The laptop? If so, I've got a built-up box - I picked a 6 core AMD processor, and compatible motherboard. I don't have a mfg as such to go to.
if you are referring to the cable, I have the disc, and it gets me no where.

The cable. Mine has a name and model number on it, which I put into Google, and it came up with a download page for the Windows/Mac drivers.

While your disk should work, I'd probably start feeding Google any names and/or numbers you can find on the disk and/or cable in hopes of finding something. Of course if it's a real company like Belkin you're in great shape. If it's a super el-cheapo (like mine) you just get to hope the guy and his garage are still in business.

What does the CD say? Does it say Win7? What Win7, 32-bit or 64-bit? Any idea about the cable manufacturer? What driver is on the CD, prolific, FTDI, or something else? Maybe go to their site and download the latest version?
http://www.prolific.com.tw/eng/d...
http://www.ftdichip.com/Drivers/...
These two usually have an .exe file that you run before plugging the cable.

Edit: I think one way to find the chipset used in the converter is to plug the cable, go to Device Manager. There there will probably be a item with yellow icon there (yellow indicating that something is wrong with the driver). Right click on that, do Properties, Details. There should be an ID there, which includes VID & PID. That should theoretically be enough to identify the chipset.

Hi all:
the cable is a Cablesunlimited cable, and looking carefully, it appears that it is supported for every WIN version EXCEPT WIN7! I may have just shot myself in the foot by not looking carefully at the package before buying.
Caviot empitar!
Thanks for all of your very fast inputs.
I've sent an email off to the importer, but my chances of getting a reply are about as good as finding a 3THz AVR.
I think I'm back to square one - STK500 that are OK, a machine that works great, and the two may never talk the same language.

But you said you had 2 of them... both sunlimited? I'll wager they have a Prolific chip... type prolific into google... get the win7 driver...

As Bob says, out of the 2 at least one has to be Prolific. In which case under Properties->Details you should see PID_2303. If you see something else there, here is a website that I just came across: http://www.qbik.ch/usb/devices/d... . Just enter you PID in the search field and it may give you an idea where to get the driver.

Bob has sparked my curiosity (yet again), so I just ordered a couple of the cheapest cables I could find - $1.94 each on Amazon. We'll see if they can be coaxed into working on XP and/or Win7 when they get here in a few days.

I did not believe you and therefore went there myself. I could not find anything for $1.94, but I found a few for $0.91. It is unbelievable how can they make them that cheap!

Well, that's strange. Here's what I ordered, according to my confirmation email, but I got it for $1.94 and it didn't include the 9 to 25 pin converter (when I ordered it). It was also from a different company. It looks like they've changed the listing in the few minutes since I ordered.

It will be interesting to see what I actually get, and from where it comes, but I did only pay $1.94 each for them.

We know the Rules Of Thumb for cost per square inch of circuit boards and the cost of the silicon... that part the US can probably compete with. Its the final assembly where a tech puts the chip in the USB cable and does X steps for Y minutes. If Y is 5 minutes, he can build 12 an hour. This labor cost is $2/12 in Shanghai and $20/12 loaded in the US. So the differentiator is labor cost. If Comrade Obama would just send his Union Organizer buddies over there and convince the assembly techs that they havent quite achieved Chairman Mao's Worker's Paradise where everyone has more than a Blue Coat and a table radio and a bicycle. How about a Color TV and a car? For that they are gonna need a raise. The Sooner the Better. One problem I can see is the factory owners probably chase union organizers away from the gate with Kalashnikovs.

The plot thickens. That is the picture and listing (different price and company) that I ordered from.

OK. I'm ordering the same parts. When you get it working, please publish the missing link - the drivers.
Then I'll buy you all bumper stickers in honor of Chairman Obama.
If you can't get it working - cable for sale - $0.39 each.

Oh well, oh well, oh well. "Florida" Bob is on the run again and stroking his gun. I have explained that to you already a few times. The name of the game is QBZ-95 http://en.wikipedia.org/wiki/QBZ-95 not Kalashnikov.

A gun nut who can't distinguish a Kalashnikov from a QBZ-95. Oh dear, oh dear. Please report to the authorities for reeducation and give your NRA membership card back.

And by the way, as also already explained to you in the past, Chinese factory owners are often the union organizers in their factories. Why should they chase themselves away?

Stealing Proteus doesn't make you an engineer.

Back to Bob Gardners' suggestion. I loaded the Prolific drivers. Nope! Still can't get Studio to "see" the STK500. I suppose it could be a bad cable [just my luck], but the cable is new, and appears to be undamaged - for now - I'm not far from dropping it in a wood chipper.
Out of options, I may now have to break down and buy an STK600.

I bought a cheap no-name converter cable from eBay and failed to get it to work with Win7 64 bit after innumerable drivers from innumerable places...it went in the bin

I mentioned that before. If I have a problem with a COM port, I usually go into Device Manager to see the COM port number and possibly to verify some other settings.

In AVRStudio, did you select a specific COM port or let it find one automatically?

To test the cable, you could use a terminal utility and short the receive and transmit pins. Then in the terminal utility you should get an echo as you type characters. The receive & transmit pins are pins 2 & 3 on DB9 (or DE9). See, for example: http://www.nullmodem.com/DB-9.htm
There used to be a HyperTerminal on Windows, but I vaguely remember that it is no longer there on Win7. If you do not have one, you may want to search the forum for suggestions.

Since you had several STK500s, I do not think your problem has anything to do with STK500. In which case STK600 is not going to help. If you are willing to pay for an STK600, I would first invest into a good USB-RS232 converter that is guaranteed to work. FTDI-based, for example. Which you can get from Mouser or Digikey.

I dont have an NRA membership card but I do have a Florida Concealed Carry Permit. The questions on that test didnt ask about Warsaw Pact assault rifle make and models I guess. I did shoot a MAK-90 at the local range. Since that is a "Chinese copy" of an AK-47, my feeble mind just assumed that that is what the soldiers were going to be carrying when the human wave assaults commence. The point I was trying to make is that the reason the chinese usb cables are so cheap has to be the labor cost. I think the US needs to start manufacturing stuff again, and start using domestic oil. Lowering the wages of US workers to match the ChiComms so we could compete with them is an idea, and raising their salaries is another. How we extrapolate from worries about trade imbalance to stroking guns seems like a stretch. I just hope they dont call in their loans.

Yours had a test? In Washington State about the only questions are "Name:" and "DOB:" and "Will you give us $50?".

Back on topic - Amazon just shipped my cables. I'll take out my money's worth in complaining since shipping will be too expensive to return them.

If we become like Florida then it will rain every day at 3:00 for 15 minutes rather than all the time like it does now. That wouldn't be right.
