I basically uninstalled all com drivers, Avrstudio etc to make sure I had a clean install.
I reinstalled AVRStudio 4
Installed com0Com and set ports to 4 and 9
Installed USBTiny500
In my device manager I have
.. Com4 and Com9 listed under Ports and are working properly.
.. com0com is working properly.
.. libusb-win32 working properly.
When I use USBTinyISP, swapping between 4 and 9 gives Opening port COMX and then hangs there.
If I close USBTinyISP and reopen, it says READY.
Needless to say, AVRStudio cannot find the port.
AVRStudio does work with Polopu progammers.
Thanks and frustrated !!!!!

Re: AVRStuido Cannot find serial port. Win7
That was always a hack, not guaranteed to work.
You can configure newer versions of Atmel Studio to use the USBtinyISP directly through avrdude:

Re: AVRStuido Cannot find serial port. Win7
Thanks for the reply. The new versions are full of bloat ware and takes ages to load. I'm writing short ATMEGA code and ver 4 suits me fine.
I don't think the problem is with studio. I think the USBTiny500/com0com is not working correctly as when I select a com port, Tiny does not come back and say ready. It hangs saying connecting.
I've uninstalled and reinstalled twice so something is not compatible somewhere.
Is there any other software hacks I can try?
Thanks Wallace.

That's what I meant before - the com0com stuff is a hack and is not guaranteed to work.
I don't know what else you can do.
