I have my Dwarf hosting two MIDI devices that require power over USB. The Duo’s host amperage is higher so I was able to host and power these with an unpowered hub. However, I need to power the hub when using these with the Dwarf. But the super weird thing I’ve noticed when doing so is that if I need to restart the Dwarf and I unplug its power connector, it doesn’t fully power off but rather sound stops being processed and the screen, LEDS, buttons and knobs continue to work until I disconnect power from the USB hub. That seems wrong and somewhat scary. I don’t want to damage my Dwarf with a brownout! Is this OK?
Also it seems to confuse the Dwarf as to which MIDI devices are connected and they become unresponsive until I do some combination of restarting the Dwarf/hub and using the WebUI to get everything back up (haven’t figured out a combo that works every time, which I’ll need if I’m on stage and things start acting up). And is there another way to restart the Dwarf without unplugging it or using the WebUI?
UPDATE: It’s this hub that uses a USB A to USB A cable. Tried a different powered hub with a USB A to USB B cable and the Dwarf powers off when I pull its power cable. Seems like I have to use a different hub!
What sucks is that I have this hub that works flawlessly with my Duo but its USB A connector is loose in the Dwarf and therefore only works intermittently (and same problem when I plug it into my laptop). Why can’t these things be standardized for real???
