USB: FPGA to host communication - the same old story

Hi altera forum users,

I know this was already podted many times and read all the topics about that, but nothing works for me.

I want my PC as host and want to communicate with my FPGA design via USB. I have Terasic's famous DE1 Board and Quartus II 11.0sp1 Web Edition.

I have tried many ways, but nothing worked for me:

-using jtag_atlantic.dll doesn't work because I don't have vc++

-altera_jtag_to_avalon_mm_tutorial.pdf is a nice tutorial, but the communication based on quartus_stp, that's annoying!

-image_download_demo doesn't work because I don't have vc++. I could use eclipse environment too, but I don't know how it works in eclipse.

Please help me! I want to send/receive some bytes to/from the FPGA.

It's really annoying that Altera's USB programming support is so bad.

    In the console of the IDE (as well as the stand alone terminal application) can input keyboard commands and get results from your NIOS-2 on the DE1. For this you can configure your standard IO to use the JTAG-UART. If you write a command interpreter on your NIOS-2 can can control your NIOS in this way from your PC.

    You mean writing a TCL script and run it in the system Console? I don't have experience in writing tcl scripts, I don't even know how to run a script with parameters (args).
