Hi Ubuntu and Linux Team, I have been observing the attached dmesg output with several different ASMedia 3142 Cards whilst doing usb bulk transfers using the linux read and write api's to a usb device. This tends to break the software invoking said API's. I am using Ubuntu server 18.04.3 with kernel 4.15.0-55-generic. I see this issue with both Intel and AMD based computers.
Has there been an update or patch or change in priory that might resolve this bug?
