I wrote an article on "softcombing" and tried to put the article in Wikipedia. I could not find references. So the article is going to be discarded. How can I get references from the internet? There is a video clipping in YouTube on softcombing. But it is not acceptable to Wikipedia. Do I have to write a book on softcombing? Can someone else give references for me?

Why is it that some devices only support a limited amount of external memory? I have two 64GB SD cards, and neither of them works in my phone (Samsung Galaxy SIII mini) or my wearable action camera I use for cycling. They bot have to use a 32GB one.

In any case, I won't comment on the rest, but it seems to me that BenRG had a very good point if they were correct and it's a point I myself have mentioned before, possibly somewhere on wikipedia but if not elsewhere. If the only real difference between SDXC and SDHC is the file system and capacity, then there's no particular reason why most SDHC devices can't support a SDXC card formatted with FAT32. Definitely it's known that many devices which only advertise SDHC support have no problem with FAT32 formatted SDXC cards. (To be clear, these devices don't necessarily support SDXC, as they may not be able to work with exFAT. Although some do, so you could say they are apparently compatible even if not officially compatible.)
This isn't to suggest devices can't have problems. Technically since the SDHC standard says the card size must be limited to 32GB, a device could either either not understand or simply refuse to work with such a card (although IIRC last time I checked, the standard also doesn't seem to say it has to). And there may be other reasons relating to the implementation why a device wouldn't work with such a card (e.g. the software was limited to working with 32GB partitions).
And while there have been numerous reports of devices working with SDXC cards despite only officially supporting SDHC, IIRC there have also been reports of some devices which wouldn't even when the card was FAT32 formatted.
It's perhaps also worth considering other factors. I believe some devices seem to have problems with newer high speed cards, e.g. UHS-II. While this is part of both the SDXC and SDHC standard, its introduction postdated the SDHC standard by a while so it's perhaps not so suprising some devices can't handle them (and I think history in many areas has show theoretical backwards compatibility doesn't always translate to practice). I think you're much more likely to get a SDXC card in such a speed, so you're unsurprisingly also likely to encounter problems (although it wouldn't be accurate to say the device doesn't support SDXC cards per se, since technically you can have a SDXC card that's speed class 2.
Incidentally, a significant counterpoint here is SD(SC) and SDHC. SDHC introduced a different way of reporting capacity etc rather than simply using more bits to allow a larger capacity. Therefore it's hardly surprising that a large percentage of SD(SC) devices don't work with SDHC cards. I believe there is some similarity with 4GB SDSC cards in that if you follow the 1.01 version of the standard, there's no reason why you can't have 4GB cards, except that the standard says they're limited to 2GB. (Note that there is an added complexity on that devices only supporting 1.00 may not work with 2GB or 4GB cards. As I understand it, this isn't simply the standard limiting the maximum, but a feature wasn't even implemented yet so there was no reason for devices to be expected to support it.)
Getting back to the OPs original question, even if it turns out BenRG and me are wrong about the standard, I stick by my other claim which was also mentioned by BenRG. Many devices which don't claim SDXC compatibility but only SDHC will have no problem with a FAT32 formatted card. Note an important point here, some devices, even though normally capable of formatting cards, may refuse or otherwise be unable to do so with a exFAT or SDXC card. So if the OP hasn't tried formatting the card in a computer or similar first, they may want to do so and confirm it doesn't work after formatting. (Since Windows refuses to format FAT32 partitions larger than 32GB, the OP will need to find ways how.) The fact that the device is nominally incompatible with SDXC or even the differences between SDXC may not be so important to the OP if their devices can actually work with the card, they just haven't worked out how.
I had a look around. It's difficult to find much since I'm getting a lot of stuff relating to the non mini (which I think official supports SDXC or at least 64GB cards). I did find [1] which may sound disappointing, but if you read the last post it sounds like they may have eventually gotten it working. Some more searching using quotes found [2] and h4wkst3p [3] find other reports of it working in a stock situation. (Unfortunately I still got a lot of junk posts such as people saying it doesn't officially support it so it won't work. Or the S2 which doesn't officially support it either has been tested to work with SDXC cards so it's better than the S III mini despite no evidence the the person has even looked for reports of the S III mini and SDXC cards.)
