I’m trying to talk to an Ultegra Di2 system via my Mac. So, I loaded up Parallels, installed Windows 10 as a virtual machine and downloaded the E-tube project. When I fire up the application, it comes up with the SM-PCE1/SM-BCR2 connection request but when I then plug in the SM-BCR2, nothing. I have looked through various device & driver control panels and all seems to be in order and updated. I have tried all the obvious unplugging/shutdown/restart rituals but still no joy.
I’ve been using this with VMWare Fusion and Windows 7 for quite a while - do you see Windows searching then downloading a driver for the PCE1/SM-BCR2 when it’s plugged in? Try connecting it without first starting the E-tube software and see if there’s any indication of Windows loading drivers for it - you should see a popup in the notification tray.
Thanks, some progress but not quite there yet.
Connected before launching e-tube, didn’t see any attempt to update anything, looks like driver is ok.
Checked within Parallels that it is connected to Windows.
Launched E-tube and it went through a recognition process, determined that there was a firmware update available, went through the download etc but then went back to asking for the BRC2 connection.
Yes, it was still connected to Windows. So I toggled it back to Mac and then back to Windows. This seemed to help in that it went through a recognition and tried to do a firmware update, but then back to connection request.
Toggling back and forth seems to wake it up. It then tries the firmware update but doesn’t look like it finishes it.
On a re-plug I then get a Parallels message saying unable to connect BCR2 to your VM now, try again later. So maybe a stability problem through Parallels?
I have one day left of my parallels trial so I’ll try fusion, thanks for the tip.
Problem solved! By toggling back and forth from mac to windows rather than unplugging/replugging, it went through a series of recognition steps and firmware updates until everything was updated and now I can see all the components in the window.
Came across this thread and thought it has substance for a “how to” article for the homepage. LOTS of Mac users among our readers. Honestly, given the popularity of Macs among cyclists, I’m shocked that this is a Windows-only app. So I’m wondering if one/some of you might want to put together a basic guide for using e-tube on a mac. I’ll edit it.
