Установка драйвера для NFC-картридера ACR1251 на BBB под управлением Debian 8

На плате BBB используется один из последних дистрибутивов GNU/Linux Debian 8, в котором есть пакетный репозитарий.

Мы подключаемся по RS-232 к BBB через собранную на коленке плату-конвертор. Подробнее тут . На нашей рабочей ОС Ubuntu 14.04 amd64 зайдем в терминал и установим связь:

sudo screen /dev/ttyS0 115200,cs8 

Подключим BeagleBone Black через коммутатор к сети и поставим уже собранные пакеты демона (pcscd) и драйвера (libacsccid) (middleware-библиотека libpcsclite уже стоит):

sudo apt-get update
sudo apt-get install pcscd

sudo apt-get install libacsccid1

Команда lsusb (sudo lsusb) видит картридер ACR1251:

Однако, несмотря на ошибки, картридер корректно выполняет чтение и запись на карту. Моё приложение, использующее динамическую библиотеку libpcsclite, корректно работает (даже при соединение через USB2.0 Hub, что по непонятным для меня причинам мешало работать другому картридеру ACR122, возможно, поддержка последним только USB1.0 (?)).
