Description
For some reason, pySim-prog.py fails to program a SIM card when using Python 3.
Using PC/SC reader (dev=0) interface
Ready for Programming: Insert card now (or CTRL-C to cancel)
Autodetected card type: sysmoUSIM-SJS1
Generated card parameters :
> Name : Osmocom
> SMSP : e1ffffffffffffffffffffffff068100095155f5ffffffffff000000
> ICCID : [REMOVED]

At the same time, reading a SIM card works just fine. Switching back to Python 2 makes pySim-prog.py work again.
I grabbed debug output of pcscd using the following command:
$ sudo LIBCCID_ifdLogLevel=0x0007 pcscd -fd | tee /tmp/pcscd.log
Please seee attached files and the difference between them.
