** This post is about a device called a Continuous Glucose Monitoring System (CGMS). Read more about them here.
One of the complaints I had about the Dexcom 7+ was it’s stupid proprietary power and PC cable. The G4, despite it’s universally-defined micro-USB connector, has managed to accomplish the same damn thing.
To do this, Dexcom made it so that you MUST install the Dexcom Studio software on a compatible machine to be able to charge it without using the supplied AC adapter.
Instead of the proprietary cable, you must use their proprietary software.
You must have the software installed, NOT RUNNING BUT SIMPLY INSTALLED!
Not to download data, but to simply charge the damn thing.
That literally toggles my “WTF” face…
This means you can’t simply plug it into a computer anywhere.
This means you can’t use an external battery pack like you might with your phone or tablet.
This means that you can’t use a car charger.
The only other option is to use the AC adapter supplied with the device, which I have to assume is proprietary as well.
Now, in all fairness, their FAQ does say that you need the software to charge it. But honestly, this is such a deviation from any other device that uses a USB connector, it should be a much more prominent point.
I shouldn’t be surprised, the whole industry loves to do crap like this.
The other issue I have is that my device will only charge on a USB 3 device, not a USB 2 device. Even plugging the cable directly into the machine, no hubs involved, it will only charge on a USB 3 port.
Calling tech support, I was informed that they had never heard of this before and my issue would be forwarded to the “leadership group”, whatever that is. Back in the day, IBM support would tell you that “you are the only installation in the country experiencing this issue”. Then all of a sudden message boards started popping up, people started talking about these issues and IBM eventually stopped using that “only installation” line for some reason… Speaking with tech support about this problem today reminded me of those IBM support calls. A lot.
What possible benefit is it to Dexcom to make this device this proprietary? It is certainly of no benefit to those of us that must use the device.
Seriously, proprietary to simply charge?
I’ve been happy with the increased range and accuracy. Not to mention that the sensors last quite a while. I’m not going to stop using the device.
I am, however, going to keep asking why decisions like that are made. Decisions that make it harder for patients to use the product.
If anyone can come up with a rational explanation for the software requirement to charge, I’d love to hear it.
That includes you, Dexcom.
