The select command mostly works when the blue sysmocom SIM card is inserted,
but with the white SuperSIM we always get timeouts and invalid answers.
Furthermore the white card takes much longer to answer the requests than the
blue one.
So probably there is a timing issue.
Currently this is the simtrace output for select and reading IMSI, etc:
(pcscd must be running as welil, otherwise we get:
$ ./simtrace.py -S
Exception: Failed to establish context : Service not available.)
$ ./simtrace.py -S
Context established!
PCSC Readers: ['ATMEL AT91SO CCID Smart Card Reader [SIMtraceCCID] 00 00']
Using reader: ATMEL AT91SO CCID Smart Card Reader [SIMtraceCCID] 00 00
Connected with active protocol 1
Select: 0x6E 0x00
Command: 0x6D 0x00
Disconnected
Released context.
==> Expected answer for Select: 0x6D 0x00
(based on trying to execute this command with gemalto usb smart card reader)
The command works only every now and then
$ ./simtrace.py -b
pcsc: wait_for_card

==> Error code 9404 does not exist, which suggests that we actually have a timing issue when
communicating with the smart cart
Switching to config 1 and 2 works, but to 3 and 4 usb_enum.py is
hanging for some reason. Switching the USB config from Sniffer to
CCID reader was not tested yet.
