[Pcsclite-muscle] Registering virtual readers

[Alexander May]

Hi,

first of all I'd like to thank you for your detailed responses. I was
able to implement my driver now as I wished (using a hacked version of
pcscd). That's great.
Nevertheless I'll need to provide clean solution (at least on Ubuntu
12.04 LTS) and before delivering a patched version of pcscd I'd like to
make sure that  this patch will be accepted upstream.

I digged through that code in hotplug_libusb.c. There detection of new
serial readers is essentially handled by call to RFReCheckReaderConf().
As of my understanding of this code it checks all configured serial
readers and removes unresponsive readers and adds new readers that are
responsive now. This is what I would expect from pcscd -H, regardless of
the used hotplug flavour.

My current solution simply call RFReCheckReaderConf() from signal_reload().
Did I miss anything important here? Why would you want the checking of
serial readers to be forwarded to the hotplug library if the initial
setup is handled by pcscdaemon.c itself (calling RFStartSerialReaders())?

As described above would you accept a patch that removes the
RFReCheckReaderConf() from hotplug_libusb.c and instead moves it to
pcscdaemon.c where it can be used by all hotplug-flavours?

Regards,
Alexander
