I went out to check for this stuff in real life. A store that sells stuff (relatively) cheaply had a usb hub for about $5 with 4 slots and a separate shutoff for each, but it was 2.0, not 3. Best Buy had a bunch of hubs, even under $10, but they went way up from there. What's the good of having a hub that mentions only computer stuff, not Android? I guess there are some that can handle it all, but it's a mine field. Why doesn't somebody sell a 3.0 with the otg cables included? That would have to be a lot easier than trying to assemble it piecemeal. What's that great about otg cables anyway, and why can't I find any? There are plenty of charging cables, Lightning, braided, etc., but not otg. Meanwhile, are photos exempt from all this? If PDFs, epubs, and all that are separate from FAT v. ntsf, are they separate too? Maybe jpeg for instance could fit on a hard drive with ntsf and no conversion needed. What does ntsf really mean?
