USB-Blaster conflicts with other FTDI device

Hello Team,

I'm currently programming an FPGA with USB-blaster.

My computer is also using other FTDI device.

However once I activate other FTDI device , "quartus_pgmw.exe" can't control USB-blaster anymore.

I cross check it , found out the API which Quartus II is using might conflict to other FTDI device.

Is there any way can make them both work?

Thank you for any information you can provide.

Yes, you can use multiple USB blaster II as a workaround since it does not use FTDI chip.

Thank you very much Vikas.
I see there are some people using USB-blaster II to fix this problem.
My PC currently connected other three FTDI devices would it workable with another two sets of USB-blaster II?
Thank you for any information you can provide.
