Hey guys I've been mucking around all night trying to understand the process to update DI-20 firmware. I've gotten this USB blaster, Windows 10 and downloaded/installed Quartus 16, which was confusing as heck because 12.1 the manual refers to is no longer available and Quartas is apparently the same as Altera, but has changed hands to Intel FPGA software, then opened up 3-4 separate applications on my screen after install.
Following these instructions, I've connected the USB blaster to the DI-20 update port and to the PC which auto. installed the driver. Then for step 3 on Audio-GD instructions I powered on the DI-20 but "Perform automatic web license retrieval" was not there because I'm using newer version 16, 12 being obsolete, so instead clicked a button in the control panel to activate a trial.
Here's where I'm stuck: Under step 5 for the hardware setup I'm not seeing any USB Blaster on the dropdown menu. Also on the USB list on my device manager I'm only seeing "Unknown USB Device (Device Descriptor Request Failed)", in fact 2 duplicate entries saying this. I've tried the steps mentioned by user @DACLadder to manually load the Blaster USB drivers, but every time I get the message that the best driver is already installed. Removing/reinstalling the USB driver just brings up the same set of 2 "Unknown" devices on my device manager. I thought to install the newest Quartas version 20.2 standard version (it took me to 20.1 instead), which made me register on their website with loads of personal information and download a 2.1GB file. I'll try this newer version next, if it's even the way to go in my case??
