writing midi settings results in exceptions and errors

[TheTechnobear]

steps
board->midi routing
refresh
write settings

leads to following errors.
also it appears the routing is not working on the board.

as toggle->midi/out/clock run leads to midi overflow (as no device connected?)

note: this is 2.0.0

also prior to this board is connected, and is able to run patches...
so its unclear why the get the control transfer failed - which leads to disconnection and then ultimately other errors.

[TheTechnobear]

ok, the issue is
[code]
at axoloti.connection.USBBulkConnection_v2.createDirectory(USBBulkConnection_v2.java:1012)
at axoloti.connection.USBBulkConnection_v2.createDirIfNonExistant(USBBulkConnection_v2.java:579)
[/code]

whilst its attempting to create the midi-out directory, it does not create the settings directory

workaround: create the settings directory manually on the card, then it will work

fix: check for settings directory, and create if necessary.

EDIT:
Q. is, do we fix this by changing USBConnectionv2.createdirectory to split up path, and then create directory above, as necessary..
or do you want to do this on the firmware side on the board?

[JohannesTaelman]

Can't reproduce this issue, after deleting the settings directory, it is recreated when I do: board->midi routing, refresh, write settings...
Missing parent directories are created in USBConnectionv2.upload().
The real issue is perhaps something else than missing parent directories.
