wstawiam journal z poszukiwania rozwiązania na dziełający czytnik kart SD w laptopie ASUS PU 551.

sprawdziam markę i model czytnika kart?

admin@PU551:~$ lspci | grep -i Card
02:00.0 Unassigned class [ff00]: Alcor Micro AU6601 PCI-E Flash card reader controller

w internecie są porady aby zainstalować ten sterownik 

sudo add-apt-repository ppa:iacobs/au6601
sudo apt-get update
sudo apt-get install au6601

pierwsze polecenie zwraca błąd, odszukuję bezpośredniej ścieżki do pliku .deb

nadal nie widać karty pamięci

tworzę katalog i próbuję montować:

nie działa, zamraża konsolę, zamraża też inne polecenia dotyczące dysków
