Cannot upgrade with the ReSpeakerMicrophoneArrayDfu tool

[jongerenchaos]

I start the ReSpeakerMicrophoneArrayDfu.exe tool with administrator access but i get the following error:

Device opened. Ready for firmware update.

Entering upgrade mode... TUSBAUDIO_GetDfuStatus: Function failed with error code 0xEE000003.

Firmware upgrade failed!

How can i resolve this (current version V0.31)?

Can you have a try as following:

1. Open Devices Management(windows) and find your mic array device.
2. right click and uninstall the device(select checkbox of "uninstall the driver")
3. remove your device from USB, and plug in again.
4. reinstall the driver by setting the location of respeaker mic array driver where you install it.
5. try to update again.

Change to another PC with win10 and it worked!

I've got the same problem - can't upgrade. I've tried on the PC (Windows7 Pro, 64bit and Parallels Win10 on a Mac) with the same error:

and also tried natively on a mac using xmosdfu with no luck:

I have 2 microphone arrays and both exhibit the same issue. The array serial number is 107010001, purchased in the last month.

What is going wrong?

I'd propose to try another cable. Solved my problems with upgrade.
