I don't know yet where the problem comes from.

Can you edit the file
/usr/lib/pcsc/drivers/ifd-ccid.bundle/Contents/Info.plist (it may be
called /usr/local/pcsc/drivers/ifd-ccid.bundle/Contents/Info.plist if
you installed pcsc-lite and the driver yourself) and change
"ifdLogLevel" value from 0x0003 to 0x000B.

Then kill pcscd and restart it with:
$ pcscd --foreground
or
$ pcscd --foreground --debug (if you use pcss-lite 1.2.9-beta7)

Insert your GemPC Twin reader, insert your card, exchange one or more
APDU and send me the pcscd output.

Bye,
