Dear maintainer,
This appears to be similar symptoms to bug #459827, but reporting
separately, as this has nothing to do with PCMCIA.
After removing a Yubikey 4 (USB-C) from my XPS 13 9360, syslog is filled
with errors like this about once a second:
```

```
This specific issue happened after a resume-from-suspend when the device
was removed between suspend and resume, but in general it happens any
time I remove the USB-C device.
This does not occur with a Yubikey Neo (USB 2.0).
I was also able to replicate it on a fellow developer's XPS 13 9350.
Please let me know if there is any other debugging information I can
provide.
Yes, you can help me.
- Get the pcsc-lite source code.
- Edit src/hotplug_libudev.c and change line 66 to:
#define DEBUG_HOTPLUG
- rebuild pcsc-lite
You do not need to install it.
- kill any already running pcscd process
- run the newly compiler pcscd
$ sudo src/pcscd --foreground --debug --color | tee log.txt
- connect the Yubikey 4 (USB-C)
- disconnect the device
- stop pcscd by Ctrl-C after the problem occurred
Send me the generated log.txt file.
Thanks
