Poll Mini Maestro 24 Channels - USBProblem on Ubuntu 14.04

I have a Pololu Mini Maestro 24 channels and I am trying to access it from my linux machine (Ubuntu 14.04).

When I run lsusb I get:

Bus 001 Device 007: ID 203a:fffa  
Bus 001 Device 006: ID 203a:fffa  
Bus 001 Device 005: ID 203a:fff9  
Bus 001 Device 004: ID 203a:fffa  
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 006: ID 1ffb:008c  
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So I have the Bus 002 Device 006: ID 1ffb:008c that I think is good…

And then when I do dmesg:

[ 1829.281366] usb 2-1: new full-speed USB device number 6 using uhci_hcd
[ 1829.415530] usb 2-1: New USB device found, idVendor=1ffb, idProduct=008c

[ 1829.452351] cdc_acm 2-1:1.2: ttyACM1: USB ACM device
parallels@ubuntu:~/Desktop/maestro-linux$ ^C

Then, when I open the MaestroConrolCenter, I get:

“There was an error while starting up. Error connecting to device to get serial number (8 of 9, 03198be0). Access denied.”

Do you know what this means? How do I get passed this error message and get “access accepted”?

The green LED is steadily on and the orange one is blinking slowly. Shutting down my computer and unplugging the Maestro Mini doesn’t work.

Thanks!

Hello, Emma.

The file README.txt in the Maestro Linux software download has these instructions:

You will need to copy the file 99-pololu.rules to /etc/udev/rules.d/
in order to grant permission for all users to use Pololu USB devices.
Then, run

sudo udevadm control --reload-rules

to make sure the rules get reloaded. If you already plugged in
a Pololu USB device, you should unplug it at this point so the new
permissions will get applied later when you plug it back in.

Did you follow those instructions?
