Alcor Micro AU6601 PCI-E Flash card reader controller on ArchLinux

I'm running ArchLinux on this perfect ASUSPRO BU401LG notebook by ASUS and the only problem I faced recently was sd-card reader not working at all.

lspci shows the following:

There are no events in logs after inserting sd-card into slot. So, after a bit of searching here is the solution.

Thanks to Sabin Iacob there is a driver for the card reader and the only thing to do is to install it.

Driver is packaged for Ubuntu and these are the steps I've done to install it on Arch:

• download appropriate deb-package (i386 or amd64) from packages page
• install debtap package from AUR if not already installed
• initialize debtap database
• convert deb package to archlinux package using debtap
• install generated package using yaourt -U
• install kernel driver
• use card reader :)

$ wget https://launchpad.net/~iacobs/+archive/ubuntu/au6601/+files/au6601-dkms_0.3-0~ppa7_amd64.deb
$ yaourt -S debtap
$ sudo debtap -u
$ debtap au6601-dkms_0.3-0-ppa7_amd64.deb
$ yaourt -U au6601-dkms-0.3-1-x86_64.pkg.tar.xz
$ sudo modprobe au6601-pci
$ udevil mount /dev/mmcblk0p1

# profit!
