[Pcsclite-muscle] Not enough reader entries on CentOS 7.0 with pcsc-lite 1.8.8

[Daniel Abson]

Hi there

I've got 60 OmniKey 3121 readers attached to a server running CentOS 7.0 (x86_64). I have the latest OmniKey drivers installed (ifdokccid-lnx_x64-3.9.0). All devices are listed by lusb, but only 16 readers are showing up in my Java client (which is using javax.smartcardio).

Running systemctl status pcscd -l shows the following output:

pcscd.service - PC/SC Smart Card Daemon
   Loaded: loaded (/usr/lib/systemd/system/pcscd.service; static)

I have also tried manually setting --max-thread, --max-card-handle-per-thread, --max-card-handle-per-reader to 200 in pcscd.service, with no effect, but the default for pcsclite at this version should be 200 anyway. I'm not sure what I'm missing - can you help?
