TOPIC:

I have MCHStreamer Kit 211-2622 and driver version MCHStreamer_MCHStreamer_Lite_20220314. Driver installation succeeds but the firmware updates not. There is always this error:   Entering upgrade mode...
   TUSBAUDIO_GetDfuStatus: Function failed with error code 0xEE000003.   Firmware upgrade failed!

How to fix? Do I need newer firmware versions, can you provide?

Hi,
I have the same problem... tried with the two MCHstreamers I have (211-2616 & 211-2613). It also appears as MCHstreamer Lite in the firmware upgrade application (see the attachment).
The driver and application are from "MCHStreamer_MCHStreamer_Lite_20220314" that by the way seems to contain an older driver (miniDSP_UAC2_v5.12.0_2021-05-30_setup.exe).

Please advice...

 

Hi,

miniDSP support team provided a fix for me. Before and during the firmware update certain two points in HW needs to be shortcut. See attachment for details.

Hi, I get exactly the same error but with an MCHStreamer Lite. 

The weird thing is that I flashed it about a week ago with no errors. I've had a Windows update since then though, and myself and my colleague have the same problem.

The fix that was posted above doesn't work for the MCHStreamer Lite because it has a different board layout.

Any ideas?

Thanks!

I can confirm problem&fix on a newly bought (April22) MCHStreamer
(fix was not so easy with tweezers -- had to make a solder bridge)
