I just bought a ReSpeaker Mic Array v2.0 Module and encounter installation difficulties.
I am using a Raspberry Pi 3 with Raspian 9 Stretch.
I did the steps mentioned in the wiki:
The last comand throws:sudo apt-get update
sudo pip install pyusb click
git clone https://github.com/respeaker/usb_4_mic_array.git
sudo python dfu.py --download 6_channels_firmware.bin # The 6 channels version
See Image.usb.corecUSBError: [Errno 32] Pipe error
Google has been to generel with this problem (At least for me)
Thanks for all responses.
