I just connected my Android device to OpenBSD, and since I did not find any article on this subject, I want to share my experience.
OpenBSD supports USB Mass Storage Device (used in usb drives) with umass(4). But Android uses MTP (file-level protocol, not block-level like umass), So OpenBSD launched ugen(4) to give user-space tools access to some unknown USB device. I installed ``simple-mtpfs`` package that uses fuse (user-space fs). $ mtp-connect $ simple-mtpfs /mnt and it worked! You only need to be sure that your screen is unlocked. For some reason my Android does not allow to connect to it. There is also ``devel/adb`` port to debug and install .apk, but I haven't tried it yet.
