USB timeout error with ACR122U REV 1.14C

[Toxicable]

I've been using pyscard to to read smart cards with a ACR122U readers.
However the last batch of readers I've got have a new PCB revision, they're the same model but the PCB's are now "REV 1.14C" compared to the old "REV 1.14B".
Comparing the PCB's they're quite different, but I assume since they're the same model number that the interfaces remain working.
For Software i've been doing most of the validation on Ubuntu with these versions:

pcsc-lite version 1.8.23.

and pyscard==1.9.7

The error can be reproduced when I start the host with the reader plugged into any USB slot.
I've also validated this on another host

The service eventually goes to "Active: inactive (dead)" as reported by systemctl
However, while the service is "active (running)" if I unplug the reader then plug it back into the same usb port or another, it throws just one line

Jan 21 13:51:33 SOME_HOST pcscd[8818]: 48681205 ccid_usb.c:888:ReadUSB() read failed (1/6): -7 LIBUSB_ERROR_TIMEOUT

Then I'm able to connect to the reader via pyscard.
If I start the host without the reader plugged in then, then once booted plug it in, I'm able to access it via pyscard.
While this work around works for development, it's not suitable for deployment.

The "ACS ACR122U PICC" reader is in the Unsupported list
https://ccid.apdu.fr/ccid/unsupported.html#0x072F0x2200

You can try to use the ACS driver instead https://packages.ubuntu.com/focal/libacsccid1
