Free USB VID (Vendor ID) & PID (Product ID) for DE2 boards?

My question:

For development, I utilized open-source USB driver on DE2 board in which I selected USB parameters

x"09fb" as VID - vendor ID (Altera)

x"600A" as PID - product ID

*** Can I utilize these USB VID & PID or is there any free VID&PID for DE2 University program?

Note: I selected PID=x"600A", because PID must be different from Altera USB blaster (PID=x"6001") to assure simultaneous communication with PC on 2 USB cables, one for programming DE2 board, the second for the logic analyzer.

Explanation of project:

For my students, I have developed logic analyzer for DE2 boards with USB connection to PC. It was tested also on DE2-115. The logic analyzer is an education application written for non-profit reasons. It contains simple on-line compression of sampled data and it is capable of sampling up to 50 MHz with on-line sending data to PC, so you can see signals in real time. The complexity of the logic analyzer is about 1400 LE + synchronous on-board RAM for FIFO memory (with selectable size).

The analyzer will be tested in this winter semester by my students together with PC graphical environment written in C#. Finally, I plan to publish all as an open source, but I need VID and PID.

Thank you for your replays.
