Sure. It's even usb-powered, so you can run it off a battery. http://www.hobbytronics.co.uk/usb-midi-converter?keyword=Usb%20host
Careful: USB Host support != USB Hub support. The USB stack on this device does not support USB hubs: http://www.hobbytronics.co.uk/usb-host-midi
The USB MIDI device must be connected directly to the USB Host, it cannot be connected through a USB Hub.
Other than supplying power, isn’t a USB hub a passive device? (where, of course, the USB host is not)
Nope, it’s a device in its own right. The USB 2.0 spec has a whole chapter (11) dedicated to it. There seems to be some complicated magic involved as even the quite fully featured LUFA USB stack has not yet a driver for it in host mode. Otherwise I’d already be rolling my own Arduino based MIO 4+ on the cheap
Operating systems seem to have appropriate drivers though. One option for a cheap USB host with hub support would be a Raspberry. IIRC there are even dedicated projects for a headless USB and DIN (using the GPIO pins) Midi box.
think might have missed what @trapdoors is asking
Oh, in that case: I’ve been hooking up my iPad Pro simultaneously via a USB hub to my Keystep and OP-1 and used Midiflow on the iPad as the master clock to drive Patterning and the USB devices. I’m using the USB 3 CCK which has an input for power though.

Thanks all! Though the thread went in several directions…those are some great leads!
