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?
