USB device (re-)connection issue about main_mister

[sorgelig]

USB on Cyclone V chips is kind of buggy. It may not work with some USB hubs. It may be picky with specific devices plugged to specific USB hub ports. Basically official MiSTer USB hub is fine while other USB hubs might have less success. You may try to change/swap ports of devices on USB hub.

my usb otg-cable has only one usb-a socket and thats chained to a usb-hub.

edit: btw usb on arrow sockit (similar samish cyclone-v chip) does not have this bug. I suspect is something else not the chip. most likely the software running the usb. yep same mister software version (ported) on arrow sockit. not all cyclone V chips are bad. maybe de10nano chip is bad in general.

anyways, why does hdmi-audio source get lost after a boot (to a bmd video-audio converter device).
video come's in nicely. yes obs audio monitoring + record is on and bmd audio is in embedded mode.

edit: omg obs needed a restart. dont mind me.

Its most likely a power delivery issue on the de10nano board, because sometimes the usb-hub does not even have the power led turned on. maybe there is a very low usb power delivery limit, like 100mA or so, not at least to the full 2A.

Don't draw the power from USB connector of DE10-nano. It's weak. So you need powered USB hub. This particular issue is not present on official MiSTer USB hub board.
