Usb to serial cable question?

[electro_4]

Hi guys

Bit of a newbie question. I have a atmega 16 micro and using a dontronics avr jtag l dongle. Trouble im having is getting studio 4 to recognise it. I believe it is the cable as i have tested the hardware on another computer and it works.
I bought a "of the shelf" usb to serial cable but avr studio 4 will not pick it up.
I was wondering do i need a specialty cable.

Would you point me in the right direction or if there is related posts

Cheers

Are you saying that the usb-to-serial is not working or that the JTAG-AVR-L is not working?

Go to the "device manager" and see if Windows recognizes the usb-to-serial cable properly.

Make sure you have powered up your microcontroller. The JTAG-AVR-L doesn't get its operating voltage from usb.

What is a "sad face error"? Does it come with an error message? What is your operating system?

Sounds like you are running Avr Studio on a Mac with a virtual machine running some kind of windows. If that is the case, I think the problem is in the virtual machine.
