usb.core.USBError when trying to update firmware

[petitsurfeur]

Hi

Using a Debian 9.4 x64 Virtual Machine with python 2.7.13 and pip 9.0.1 and the Respeaker Mic Array v2.0. I have a usb.core.USBError when I try to update the firmware.

Here is the error

Can you help me ?

It should be usb permission error. Try to run the command with sudo

Hi I also tried yesterday with the sudo command. Is it normal that the firmware upgrade disconnects the USB device ?

thanks

Hi It's normal that the firmware upgrade disconnects the USB device. I used a RPI to upgrade the firmware and it worked.
