hey all! hope tuesday is treating you well. i’ve done some searching and haven’t found another thread describing this particular issue, so here goes:
i’ve got a teletype in my 104hp pittsburgh modular move case (which has a solid power supply, etc). about a month ago, the keyboard functionality stopped being quite so reliable—an hour or so into a session, the keyboard would stop responding. re-seating the USB cable had no effect. the unit otherwise kept operating though and i could interact with it through the button and the param knob.
recently, the situation worsened. i can no longer get a keyboard to register with it at all. worried that the USB bus was misbehaving, i tried a firmware update (i was a few versions behind) and the update went through with no issues. i didn’t have to re-seat the USB cable or anything—the AVR was picked up by my mac and the flash was successful. i repeated this a few times.
does anyone have any idea what might be up or how i might debug it? i’m a programmer with limited EE savvy, so i’m happy to follow more specific debugging instructions if necessary!

double edit: as referenced below, i’ve tested the keyboard w/ my computer and it functions normally.
