E1DA Cosmos ADC

[KSTR]

Thanks, @pkane, that's the needed info. There was no hint anywhere that one would need a driver for Win10.

If you've done a FW update, why not share how you did it?

Of course!

1. Install Comtrue driver (https://drive.google.com/file/d/11LDzaULXWbtP1fyH6j7sp2S2SOF5ve3x/view?usp=sharing)

2. Open the Device Manager, go to "Sound, video and game controllers->E1DA Cosmos ADC->Properties" and check that it says "Manufacturer: Comtrue":

That shows that your Cosmos ADC is using the newly installed Comtrue driver.

3. Download the CT7601_ISP_Tool.exe (https://drive.google.com/file/d/14GC1d7RgBIBfV4EkraAlvQReGkDbAAhH/view?usp=sharing)

4. Launch the CT7601_ISP_Tool.exe

5. Turn off Detect Device

6. Make sure that the VID and PID in the CT7601_ISP_Tool match those of your Cosmos ADC. You can check them in the Device Manager.

7. Turn On Detect Device. A green box should appear with a "Device 6012 is exist" message.

8. Click on the "File" button and navigate to the .hex firmware file that you wish to flash onto your Cosmos ADC. Click "Open".

9. Back in the CT7601_ISP_Tool, click on "Auto" to start the update.

Please, before you start the update by clicking on "Auto", make sure that you have a stable USB connection and don't move or touch the Cosmos ADC or the USB cable while the firmware is being written to the Cosmos ADC.

If for some reason the USB connection were interrupted while the firmware is being written to the Cosmos ADC, then that may brick the USB bridge, requiring being sent back to @IVX for recovery.

10. After a moment, the tool will say "Verifying Success". That means that the update is complete. You can now safely close the CT7601_ISP_Tool and plug out the Cosmos ADC.

My notes (before your posted) look like this:

- (re-)install Comtrue Driver (SXW_setup_WHQL_20210429.exe) first
- start flash tool (CT7601_ISP_Tool.exe)
  - uncheck "detect device"
  - set VID to 2FC6 and PID to 6012
  - check "detect device" and see if it is detected
- select file, then press "Auto"

That's the level of details/reminders required for me (you know, I'm a hardware and software engineer).

Thanks, @pkane, that's the needed info. There was no hint anywhere that one would need a driver for Win10.

The driver is required to update the firmware, to unlock the Cosmos ADC's ASIO interface, and to unlock Mono/Stereo control via Windows' default volume slider in the Sound Control Panel.

Everything else works with Microsoft's generic device driver as well.

Can you show how you connect ?

What cables from coupler to B&K?

And what cables from B&K to Cosmos ADC?

OK, looks like all the ADCiso FW's don't work (produce all zeros as output) -- I had hoped for the SPDIF version, meh.
@IVX, Latest normal ADC FW version is "CosmosAdc_V13_RIAA_768_phase_B.hex", right?

Works. Thank you, Ivan!
