Did you con­sid­er writ­ting to usb@ with your prob­lem? I have the impres­sion that your prob­lem is a dif­fer­ent one (and can maybe solved with a lit­tle quirk-entry). If you did­n’t write to usb@ I sug­gest to do it. Pro­vide them a copy&paste of your USB relat­ed dmesg out­put and of the error messages.

I only have some­times write errors, not always. And I do not have sync-resets for sure.
