New ContributorUSB Blaster Not Found In Quartus Prime
I am having an issue where Quartus Prime is not detecting the USB Blaster device. I have installed the drivers which came with Quartus Prime, the device is recognised in Device Manager and is working properly.
Versions of software and hardware:
Win 11 23H2
Quartus Prime version 23.1std. 0 Build 991 11/28/2023 SC Lite Edition
Altera USB Blaster Rev C
EPM240T100C5N Development board
I have tried the following:
1. Complete reinstall of Quartus Prime
2. Running as admin
3. Running in safe mode and disabling the Altera JTAG Server
None of the above has worked. Any further ideas or tests?

Hi,
Here are a few steps that you can try:
- Disconnect other USB device
- uninstall and reinstall the usb blaster driver
- You can also try this https://www.intel.com/content/www/us/en/support/programmable/articles/000073673.html
- If you have another USB Blaster, please try using another one and see if it works.

I have already tried these steps, except for Number 4. I'm waiting for a new USB Blaster to arrive.

I have the new Altera USB Blaster, from a different supplier, but its behaving like the first one. It registers fine with device manager however is not available as a hardware choice in Quartus Prime programmer.
FvMHi,
are we talking about an original Altera/Intel/Terasic download cable or a clone that is illegally using the brand name? In the latter case, I won't be sure if the device is fully functional.
Regarding enumeration device manager, what kind of device is displayed?

Hi,
Intel devices can only be purchase through Intel authorized distributor.
We do not ensure the device quality and functionality and also we do not provide further service if it is not originally from Intel.
Thanks.

Thanks for confirming that you are not using genuine USB Blaster. According to this recent thread, USB Blaster clones are not guaranteed to work with Windows 10 driver. https://community.intel.com/t5/Intel-Quartus-Prime-Software/Quartus-Lite-does-not-recogize-the-USB-Blaster/td-p/1576328
