@AlesandroOrtiz @xssfox Hmm. I don't use USB enough to say for sure about speeds, though I thought I remembered them being decent enough speed. (Mind you, most of my USB drives are kind of slow, so that may be the limiting factor there.)

I wonder though. If you're right, maybe they're actually limiting them on purpose? Eg switching to a lower spec connection and etc to decrease power usage? After all, with OTG you have to power the USB device from the phone's battery normally. That's also probably stressful on its voltage regulators and etc. (They used to make crazy adapters that could utilize external power, but I haven't seen those in forever.) I could absolutely see them actually limiting on purpose in such a case.
