No DFU device found

[johntyty912]

Hi, I am using ubuuntu 16.04 with python2.7 and the Respeaker Mic Array v2.0. I have a ValueError when I try to update the firmware.

Here is the error:

We can use commands like lsusb and lsusb -d 2886: -v to check the usb mic array. For example:

$ lsusb
Bus 003 Device 004: ID 2886:0018  
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
$ lsusb -d 2886: -v | grep DFU
      iInterface              8 SEEED DFU
        bcdDFUVersion                   1.10

The VID and PID of the device is 2886:0018.

similar problem. can't update firmware.

$ lsusb
Bus 001 Device 004: ID 2886:0018
Bus 001 Device 005: ID 0424:7800 Standard Microsystems Corp.

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 $ lsusb -d 2886: -v | grep DFU
Couldn't open device, some information will be missing

When I run the duf_window.py command, the device will disappear.

Hi, do you remember how you solved the problem ? i have the exact same one

[vivian0239]

Thank you! I have a same cable issue. I waste a lot of time until read this.

[steveseguin]

Couldn't get it to work on my Windows 10 pc; plugged it into a Mac though (same cable) and it worked like a charm. Oh well.

[Robopiyf]

Turns out I just need to change the usb wire.

Which port is the corrected one?
