When I try to use the JTAGICE mkII using the usb to connect to the computer it fails. When I use RS232 it works fine.

Does anyone have a suggestion. I'm planing on upgrading my PC and will no longer have a RS232 connection.

Make sure that the USB driver is installed and that the USB port can provide the necessary current.

Okay, it appears that when I installed Studio the USB driver did not install. When I try modifying the software to install the USB driver it simply ignores it and does not install the USB driver. Is there anywhere I can get the Jungo USB driver for the JTAGICE mkII.

Make sure you are logged into Windows using an account with Administrator rights. Then re-run the Studio installation and tick the USB option.

Go to Control Panel->System->Hardware Manager and un-install the Jungo driver.

Then plug in your JTAGICE-MkII and it should re-install itself.

I cannot remember doing anything difficult when I first ran a JTAGICE-II. So just click on every default prompt and away you go.

Still no joy. I'm using Windows 7 RC1, maybe thats the problem. It did at one stage complain about the INF (a service installation section in this INF is invalid) file which leads me to believe that it Windows 7 64bit. If I had the driver I could probably correct the INF.

So if you have any other suggestions please let me know.

You're kidding - Microsoft seem to go out of their way to change the driver interface on every subsequent version of Windows to ensure that all existing software breaks (presumably on the basis that they think they can have more control over future driver development and prevent Windows getting tainted with the "it always crashes" tag when really it's just errant drivers?).

Try again with something like XP which has been round long enough for the drivers to get reasonably stable.

maybe I'll try, I'll have to think about it. I'm upgrading my computer to two quad core Xeon processors with 48Gigs of RAM. Sort of overkill. Maybe I'll return to Linux. Can ~I install Office using Wine on Linux????

Which OS do you think utilises multi core processors the most?

Can't remember where I finally saw it on the Atmel site, but there is no 64 bit USB driver for Studio. However on W7 the Dragon/JTAGICE will work with Studio installed in 32 bit virtual XP.

dak664, do you mean installing it in compatability mode?

You'll have trouble running AVR Studio on Wine in Linux. More specifically, it can run with some effort; however, AVR Studio won't be able to access the USB ports at all.

No, XP under virtual PC.

It's free with W7RC...for now.
