[Pcsclite-muscle] need to restart pcscd for USB after boot

[Johannes Berg]

Hi,

Sorry, I messed up the list settings and didn't get your emails
directly, so am breaking the thread for the replies.

I would've thought something similar, but it's not actually 100%? There
are some times where it actually works. Well, at least there used to be,
now it generally doesn't, I'd have to check. But yeah, it's possible,
but without even a USB device plugged in yet at boot, what could pcscd
depend on?

Right, but there aren't really any logs.

That last error message repeats, but it continues working anyway. No
messages between the start and stop.

Which is kind of why I was wondering about how to enable the logging if
I cannot run the --foreground listed on the website; maybe just add
similar command line options to the systemd unit so it starts like that
on boot?

I'll try that too, thanks.

Thanks,
