Hello, As far as I know it is a "common wisdom" that the OTG port on sunxi-based devices such as the MK802 is rather limited in performance and capabilities when used in the "host" USB mode. For example in my experience USB 2.0 webcams failed to work in it at all, USB HDDs would only transfer up to around 11-14 MB/sec instead of 25-30 MB/sec, and a gigabit USB NIC would only go to about 115 Mbit rather than the usual 320 Mbit.
However my questions are a) why exactly is that so (only vaguely remember some mentions/explanations in old mailing list messages that I can't find now); b) do we have this quirk documented anywhere on the wiki, as it's entirely non-obvious and often comes as a surprise to new users. -- With respect, Roman
