[Pcsclite-muscle] ACR122U LIBUSB_ERROR_TIMEOUT

[Fulup Le Foll]

Hi,

I confirm that the issue describe yesterday by Valentin is easily 
reproducible. Here after the log on my laptop

Fedora-39
  - pcsc-lite-2.0.0
  - ccid-1.5.4

To reproduce:
  1) plug the reader ACR122U
  2) pcscd -d -f

Because of this bug, the reader is not visible after a boot and have to 
be unplug/plug to work. I tried to increase USB read timeout at 
ccid_usb.c:1023 with not success.

Any idea more than welcome.
