I passed as a kernel-command-line parameter: usb-storage.quirks=174c:55aa:t
dmesg says:
[Fri Mar 12 17:25:33 2021] usb-storage 4-1:1.0: Quirks match for vid
174c pid 55aa: 2400000
Without that parameter (there is an existing Quirks for my ASMedia USB
3.0 controller in the kernel-sources):
[Fri Mar 12 11:49:03 2021] usb-storage 4-1:1.0: Quirks match for vid
174c pid 55aa: 400000
NOTE: 2400000 (new) VS. 400000 (old)
The parameter is really active:
root# cat /sys/module/usb_storage/parameters/quirks
174c:55aa:t
The total number of xhci-resets is reduced:
root# LC_ALL=C dmesg -T | egrep 'usb 4-1: reset SuperSpeed Gen 1 USB
device number 2 using xhci_hcd' | wc -l
24
Together with your diff, I see in dmesg now:
# LC_ALL=C dmesg -T | egrep 'reset|SCSI ioctl error'

So, the quirk you recommended seems to silence the xhci-resets -
passed as a kernel-command-line parameter.
Furthermore, I tried via:
#1: /etc/modules-load.d/usb-storage.conf
options usb-storage quirks=174c:55aa:t
Should this be with a dot than a space?
options usb-storage.quirks=174c:55aa:t
#2: echo '174c:55aa:t' > /sys/module/usb_storage/parameters/quirks
...after system was booted into
Both had no effect.
After 31mins of uptime I still see above 24 xhci-resets.
I have attached my linux-config and full dmesg-log.
