USB Blaster driver conflict with other FTDI kit

Hi, 

I am using a USB blaster (Terasic) and on the same system I need to use two Asix Presto programmers that use the same FTDI device and (apparently) drivers.  

 

The Presto devices load up and work perfectly, but the (previously working) Blaster shows a yellow icon in Device Manager and Quartus 7.1 can't find it.  

 

Without the Prestos, the Blaster is happy. But I need all of them.  

 

I have heard that this is connected with the way that Altera configures the drivers, and have heard talk of a patch, but have no details.  

 

I would welcome any advice so I can get the devices to coexist.  

 

Thanks 

Malcolm

@avibI found the easiest solution was to buy a really really cheap USB-serial adapter that doesn't use the FTDI drivers.

This is what I bought in NZ and it solved my problem:
