I tried on 2 old pinpad readers 08e6:3478 (one Gemplus and one Gemalto)
https://ccid.apdu.fr/ccid/shouldwork.html#0x08E60x3478
In both cases I get a CCID error. The reader does not accept the
escape command 0xB6 or 0x68.

00000020 [140682182256384] commands.c:1019:CmdEscapeCheck error on byte 10
00000007 [140682182256384] Control RxBuffer:
00000006 [140682182256384] ifdwrapper.c:477:IFDControl() Card not
transacted: 612

Byte 10 is the first data byte so 0x68 here.


I then tried with a Gemalto CT710
https://ccid.apdu.fr/ccid/shouldwork.html#0x08E60x34C2

This time the command is not rejected. I get no error but I also get
nothing special on the display.
I also get no error if I use another command code like 0xAA or 0x42.
It looks like the reader just ignores the unsupported escape commands.

My source code is attached.
You need to enable DRIVER_OPTION_CCID_EXCHANGE_AUTHORIZED in the
driver Info.plist file.

Any success on your side?

Bye
