Hey hey,
I have an older USB to MIDI adapter cable, a UA0037 (probably LogiLink, sold
as Conrad Electronic). The manual does not suggest any SysEx capabilitiies to
reset/clear it. Sometimes it gets problems with SysEx transfer to/from the
connected MIDI device and will no longer pass SysEx data.
The cable/adapter will not directly react to a device inquiry "F0 7E 7F 06 01
F7"
nor does a simple dump solve it:
amidi -p XXX --dump
Is there perhaps a trick to flush or reset such adapters? I can pull the cable
from the USB port and plug it in again, yet it's at the back of the computer
underneath the desk which is cumbersome and due to many USB devices being
connected through HUBs there is no other place to plug it in.
Best wishes and thanks for any hints,
Jeanette

The infamous Chinese garbage adapter with the fantasy clef.

Just throw it away. It cannot even process chords properly without
losing data. Yes, it is the most ubiquitous adapter type in the world.
It is still garbage.
Those garbage chips are even subverting once renowned manufacturers like
M-Audio.
Your best bet is to buy a used _old_ adapter from a manufacturer like
Roland, Yamaha, old!!! Midisport (an M-Audio model name), or anything
with Ploytec chips <https://www.usb-midi.com/> or use a soundcard with
integrated MIDI interface. Those tend to work, too.
I use a Roland UM-4 (4 in, 4 out) myself.
Also if you only need a single one-directional connection, a Terrasoniq
Midi One cable is nice (ploytec chip, single MIDI plug that can do in or
out as needed, 5m cable with one side USB, the other MIDI, no idea which
plug carries the chip) but those are no longer produced it seems.

Every USB/Midi adapter I know is transparent at the MIDI layer (which is
all there is when using class-compliant adapters): any SysEx would go
out the cable rather than address the adapter.

Hi David,
in that case, under the desk it must be. For a while. I have no issues with
playing, which is good.
Thanks for the comment.
Best wishes,
Jeanette

Playing may work, I don't remember. It doesn't properly receive events
that employ running status bytes (often used for semiautomatic chords
like those produced from arrangers or from accordion chord buttons).
And it garbles SysEx messages it sends out and likely also receives.
