Cyclone 10 GX FPGA Development Kit embedded Download Cable

UPD:

Ubuntu OS on the same desktop is able to detect the cable:

Any ideas, please.

UPD2:

Windows 8 on the same desktop also is able to detect cable.

In my opinion, the problem is in CY68013 firmware.

In Win8 the situation is not really good.

Initially, the kit had name "Altera USB-Blaster II (Unconfigured)" in device manager. After I run Quartus Programmer, the kit dissapeared from Device Manager and now Win8 shown the same error - Device descriptor request failed.

But Ubuntu still recognizes it as ID 09fb:6810 Altera

Hi,

Thank you for contacting Intel community.

That might be due to issue with USB Blaster. Kindly follow the workaround in KDB below (it is also applicable for USB Blaster):

Hello.

Thank you for reply.

Your workaround did not help.

I can not reinstall driver until the device is recognized by OS. In my situation descriptor request failed, and Windows is not able to identify device.

I can note, that when I plug the device into USB port, which was not used by this device before, the device is identified as "Altera USB-Blaster II (Unconfigured)", then in ~20 seconds it dissapears and then never is recognized in this port.

I've used USBLogView to capture these events:

Maybe this will help to locate the problem.

In the device manager I've select "show hidden devices", then removed drivers for all ..(Unconfigured).. byteblasters.

After device was plugged in, it was detected as normal unknown device.

I've manually specified drivers from Quartus Programmer 21.2. Signed driver was successfully installed for device named as "Altera USB-Blaster II (Unconfigured)". After that, the device disappeared in device manager and I got the same message about descriptor request failure.

Hi,

Just to clarify, from your 1st post,

USBA - microUSB cable and CY68013- Is this not Intel/Altera USB Blaster cable? Where is this cable from?

USB Blaster to J11 connector, I can successfully scan JTAG chan, C10GX can be successfully programmed. - Is this using Altera USB Blaster?

Regards,

1. USBA - microUSB cable - this is a cable to connect PC and the kit. The blaster is embedded to kit, it contains CY68013.

2. I use Terrasic Blaster to communicate with kit. It is connnected to J11.

Hi,

Can you try the workaround from our KDB below:

I've tried your solution.

When PC is booted without JTAG service, the blaster is visible as "Unconfigured":

Then I start Qruartus programmer from inside on Q19.1 Pro.

The blaster dissapears from device manager and I get same problem - request failure.
