Hi,
Basically pcscd is congesting the enumeration SX lock, preventing
usbconfig from running because it tries to open the same USB device over
and over again. I'm not sure why, but it can have something to do with
how you start pcscd.
Can you try to use the example rules given by the pcscd packet message?
attach 100 {
device-name "ugen[0-9]+";
action "/usr/local/sbin/pcscd -H";
};
detach 100 {
device-name "ugen[0-9]+";
action "/usr/local/sbin/pcscd -H";
};
Maybe there is a bug in pcsd that it tries to open the same USB device
over and over again if there is an libusb error? Maybe it should sleep a
bit before trying to re-enumerate devices?
I'm CC'ing Ludovic Rousseau, in case he has any comments.
Hi Matthias,
Can you try this:
You can enable pcscd hotplug debug by editing DEBUG_HOTPLUG at
https://salsa.debian.org/rousseau/PCSC/blob/master/src/hotplug_libusb.c#L69
A pcscd trace would be helpful. See https://pcsclite.apdu.fr/#support
