Have a new BrewPi Spark v2. It beeps twice when plugged into the computer, but I cannot see it on the USB port. Running OS X 10.10.4 with a virtual linux box for running BrewPi. Am I missing something here? I can’t do much without it even being recognizing via USB.
You cannot see it on the host either?
Try a different USB cable and make sure the cable is pushed in well.
Before shipping, I have flashed the firmware via USB, so it should work. Unless it broke afterwards of course.
Perfect. My USB cable was not going far enough in. Fixed that issue. Now just trying to update to the latest firmware, and it is not quite happy.

I think I know what causes this. The script has automatically downloaded dfu-util for ARM, but you are running on ubuntu x86/x64.
Try installing dfu-util through apt-get. If dfu-util is found on the system, we do not download the arm version. See the TODO on line #133 
I got there…the problem is apt-get installs only dfu-util 0.5, and the script requires at least 0.7. I guess i need to build it from source?
http://dfu-util.sourceforge.net/releases/dfu-util-0.7-binaries/
Here are all the binaries. The script should check arm vs i386 and download the correct one. But you can download it manually for now.
ok, i guess i do not know how to install those binaries
nevermind…got it. had to read back through some old threads. Thanks Elco…updated to 0.4.2.
Sorry if I’m resurrecting a dead thread, but apparentely there is no way for a newcomer to post a new topic…
I’ve just purchased a BrewPi kit.
Spent some time reading the docs (confusing!!!) after some trial & error, now it seems to work fine on my desktop PC ( VirtualBox with a Debian 8 installation on it).
Only issue I’m having is a loud and continuous beep that I quit by an “echo ‘a’ > /dev/ttyACM0” command, as suggested in this forum.
However, my plan is to have it working with an Acer Aspire One netbook with the same Debian 8 OS.
And here come the troubles.
Installation of brewpi software gives no problem, but after connecting the spark to the netbook and starting linux, the spark begin to beep and keeps resetting.
Not a continuous beep. One beep. Pause.Two beeps.Pause and so on.
After linux bootup has finished, the spark continues to beep. It then stops after some minutes.
The web server doesn’t detect the board.
“sudo ls /dev/ttyA*” returns nothing.

Here is an excerpt from the output of the dmesg command, that looks interesting:

This sequence continues until it reach ttyACM33, then stops ( it seems to happen in sync with the beeps).
So the board is someway detected by the OS, but it looks like there is a communication/protocol issue. Apparentely, the system retries 33 times, then gives up.
So I’m stuck. The USB cable should be fine, as it is working when connecting the spark to my desktop. The spark is powered by the 12V power supply, so it shouldn’t be a power issue.
I searched the forum but was unable to find any hint.
Please advice
Replying to myself…
After some research I found the solution in a Ubuntu forum.
It was the ModemManager service that was interfering.
sudo systemctl disable ModemManager.service
cured the issue.
Hope it may help anybody with similar issues…
thanks for posting the solution! will help others figure it out.
