So apparently you fixed > the issue ? do you now if this patch is currently embedded on the last > update of ubuntu 18 ? How can i know ? (of course i will test to plug > my device in it this evening, but what if i still have the issue ?). I have no idea what kernel version Ubuntu is using at all, sorry. The patch you are pointing at is in the following kernel versions: 4.14.50 4.16.16 4.17.2 so anything newer than those should be just fine for you to use. hope this helps greg k-h
