[Pcsclite-muscle] index in PC/SC lite reader names may change

[Ludovic Rousseau]

Hello,

I am working on a potential change to pcsc-lite and I would like to
get your feedback on it.
What do you think about making the number in the reader name cycle
instead of always restarting at 0?

Currently, the PC/SC reader names are something like this (for 2
connected readers):
"reader A 00 00"
"reader B 01 00"

The first number is the reader "index".
The second number is the slot index (for mutti-slot readers)
See "What is in a PC/SC reader name?"
https://blog.apdu.fr/posts/2010/05/what-is-in-pcsc-reader-name/ for
more details.

If "reader A" is unplugged and plugged in again, it will be named
"reader A 00 00" again.

My proposal is to name the reader "reader A 02 00" instead (or
whatever the next available number is).
After 99 readers have been plugged in, we go back to number 00 (if available).

The number in the reader name should NOT be interpreted by the
application. Therefore, the proposed change should not break existing
code.
However, I know that developers can be very creative when using APIs
and undocumented behaviours :-)

Do you foresee any problems with my proposal?
Any comments?

Thanks
