Oh man! After look and try many usr relevant settings I found the malfactor: tlp usb autosuspend settings.
I use tlp (energy-saving tools for thinkpad laptops) and they autosuspend usb devices by default. Now I have blacklisted my midi keyboard an all is good. I can reproduce the problem this way. Seems so that the midi keyboard doesn't wake up if it once sleeping.
For all with similar problems: edit /etc/default/tlp and set USB_BLACKLIST="<device id from usbls>" or disable usb autosuspend entirely with USB_AUTOSUSPEND=0
thanks and sorry for the bother.
No problem, but we ought to test whether we can make it work with a kernel quirk. Can you please test whether it works with USB_QUIRK_RESET_RESUME in drivers/usb/core/quirks.c ?
