[all variants] avoid_reset_quirk

I have an USB stick that will output a lot of lines in syslog:

keel: [------.------] usb 2-3: reset high-speed USB device number 2 using ehci-pci

I have found that there is a file called avoid_reset_quirk in:

/sys/devices/pci0000:00/0000:00:13.2/usb2/2-3

and when I put 1 into it, the logging will stop.

Two questions:

- should this be fixed by default by someone?
- should I use a udev rule or something similar to "fix" this putting 1 into the file? (And how do I do that?)

I am confused though:

Bus 002 Device 003: ID 0951:1665 Kingston Technology Digital DataTraveler SE9 64GB
Bus 002 Device 002: ID 05e3:0723 Genesys Logic, Inc. GL827L SD/MMC/MS Flash Card Reader

The first seems to belong to:

P: /devices/pci0000:00/0000:00:13.2/usb2/2-4
N: bus/usb/002/003

So device 2-3 is at 2-4.

And device 2-2 is at 2-3.

And I changed the one at 2-3.

Which would mean the reset-quirk results from the Flash Card Reader, not the USB stick.

At which point you get:

Code:
