[Pcsclite-muscle] Help required with Microchip SEC1210 over Serial

[Tobias Girstmair]

Hello all,

I am working on a custom smart card reader for the Raspberry Pi and I 
want to base it on the Microchip SEC1210 over serial (cannot use a USB 
reader, since I intend to use the only USB port in gadget mode), which 
is supported over serial since CCID 1.4.27.

Regarding the circuit I have replicated the one from the AppNote and I 
am fairly certain that there are no faults there, as I have observed 
serial communication in both directions.
However, I am having trouble getting the reader to show up in pcsc_scan 
and gpg2.

Here is a snippet of `pcscd -adf`'s output; I've uploaded the full log 
to https://pastebin.com/HqcBTkdw since it is rather long.

(it does not matter if a smart card is inserted, the error stays the same).

My `/etc/reader.conf.d/reader.sec1210.conf` looks like this:
DEVICENAME	/dev/ttyAMA0:SEC1210
FRIENDLYNAME	"Microchip SEC1210"
LIBPATH		/usr/lib/pcsc/drivers/serial/libccidtwin.so


Please let me know if more informatino is needed and I apologize if this 
is not the right place to ask such questions and I am happy for every 
pointer I can get.

nearly forgot: I am running pcsclite-1.8.23 and pcsc-ccid-1.4.29 on 
VoidLinux.

Thanks,
	Tobias
