My guess is that this will change with the iostreams that Jef is
working on, but right now when I build libdivecomputer for iOS (where
I have no libusb / hidusb support), half the dive computers that we
actually are able to support via BLE are not compiled in (Suunto EON
Steel and EON Core, Scubapro G2, Square, Sport Matrix), as they are
ifdef'ed out depending on USBHID.

Yes, this will indeed change. Those ifdef's will be removed.

To support multiple transports per device, the dc_transport_t enum will be changed into a bitfield. The dc_descriptor_get_transport() function will always return all transports, even the ones for which no built-in implementation is available. So it's up to the application to filter out devices for which there is no suitable transport available. This is necessary to support custom transports. (With custom transports, libdivecomputer no longer knows which transports are supported. It only knows about the built-in ones.)

To query which built-in transports are available, I will also add some new api. Probably a function which returns a simple bitmask, or maybe some modification to filter out descriptors based on some extra parameter (e.g. all or only built-in).
