Can you write about the following points in your case:

1. Did you actually install MAXII files while installing Quartus II?

2. If yes, then what do you mean by "plug-in max2 to computer"? Do you have a board with MAXII CPLD on it and you are connecting the board to your computer using some cable?

3. If yes, then when you open the Quartus II Programmer (available in Tools menu) and do an Auto-Detect what kind of error messages you get? If Auto-Detect fails, there is a high chance that there is a problem with the cable (assuming device is doing well).

1.I dont know maybe, all i did was download quartus from the altera website and got the license.I am able to select it as a device(maxII) when i start a new project.

2.yes i have a maxII CPLD and am connecting it to my computer using the usb cable that came with it.

3.When i open the programmer it says "unable to scan chain. hardware is not connected."The device and cable are working cuz i use and program it at the school lab.

*when i connect the cpld to my computer it tells me to insert a cd that the hardware came with but my professor told us to just download quartus instead of using the cd cuz its updated.I thought the hardware would detect quartas automatically.Also the programmer doesnt have the usbblaster hardware option, only the byteblaster and masterblaster.I use the usbblaster option in the school computers.
