I reported this regression last week (see https://lore.kernel.org/linux-usb/20200115153714.03d5b3aa@EliteBook/T/#u) but I got no response to my email. Today I have retested with 5.5-rc7 and verified that the problem still exists. So I am resending with a different subject line to see if anyone responds. The $subject patch causes a regression on my HP EliteBook laptop with a built-in USB bluetooth adapter. About 50% of the time, a suspend/resume cycle will cause the bluetooth adapter to stop working. The dmesg log below shows two suspend/resume cycles. At time 63.928 you can see the bluetooth adapter being successfully resumed, and at time 140.969 you can see it fail. After reverting the patch, the bluetooth adapter resumes 100% of the time. I also included below a lsusb -v of the bluetooth adapter. Is there any other debugging info you'd like me to send? This misbehavior goes back at least to 5.5-rc1.
