I have a device running the 4.19 LTS kernel which just went end of life. It has some USB signal integrity issues which result in "clear tt" loops until the bus can recover (if it can). This can result in system hangs including with lsusb. Management would like for me to patch our Linux kernel to work around the problem thinking that a kernel fix is much less costly than deploying a hardware fix. There are some USB fixes in the upstream which might help. But I think I will be without community support. What advice do you have? - Jate S.
