Hello Experts and Freaks.

 

General question about USB drivers for programming.

 

With AVR Studio 4, where Stk500.exe can be used, access to USB programming devices is based on Jungo technology.

 

With Atmel Studio 7, Jungo way is sort of disabled in the benefit of atmel_winusb native driver, which is used with 7.0\atbackend\atprogram.exe...

 

When both Stk500.exe and atprogram.exe need to be used, it leads to painful driver update switches in the device manager (browse my computer..., let me pick from a list...)

 

However in 7.0\Extensions\Application I found some Jungo DLL's: LibJungoUSB.dll and JungoInterfaces.dll. Does it mean there's some way to use Jungo with Atmel Studio 7 and its back-end tools?

 

Thank you for *technical* suggestion, any piece of advice, leads, pointers, trick, loosely related information about this question.

 

Some side consideration could be to include LibUSB0 which seems very similar to Jungo technology. It seems this driver is installed during Atmel 7.0. And also it seems it is (was) associated with Olimex tools. Not too sure, that's why I only mention it here sideways.

Zadig appears to be functional for Olimex's LUFA AVRISP2.

Zadig has WinUSB that's also in Atmel Studio 7.0.1416 and sub though, IIRC, some of the Atmel devices are composite USB (am uncertain that Zadig would be a match for those)

Zadig is a Windows application that installs generic USB drivers, such as WinUSB, libusb-win32/libusb0.sys or libusbK, to help you access USB devices.

Thank you for the suggestion. I'll look into it for finally use Atmel AVRISP mkII and Olimex AVR-ISP-MK2 both work seamlessly.

 

Anyway it seems to me (from some trials), that old Stk500.exe is only happy with Jungo based drivers, not WinUSB or libusb-based... Am I right?
