Linux kernel drivers module backport for RTS5129/RTS5139 USB MMC card reader

RTS5129/RTS5139

Overview

This is a temporary fix for RTS5129/RTS5139 USB MMC card reader on Linux 3.16+ kernels.

This ocurred during a transition from 3.15 to 3.16 kernel, as a result of the staging/rts5139 driver (which worked with the RTS5129/RTS5139) being replaced by the newer rtsx driver (which does not work with the RTS5129/RTS5139). This project reverts back to the old drivers as a temporary measure to get things up and running again.

Requirements

• make
• gcc
• linux-headers

Building

1. Checkout, build and install the replacement driver.

cd /tmp
git clone https://github.com/aurorafossorg/rts5139.git
cd rts5139
make
sudo make install

2. Blacklist the problematic modules by adding blacklist-rts5139.conf, blacklist-rts5139-dkms.conf, or this to /etc/modprobe.d/:

blacklist rtsx_usb_sdmmc
blacklist rtsx_usb_ms
blacklist rtsx_usb

3. Then, make sure you generate modules.dep and map files.

sudo depmod -a

4. Finally, disable module autoloading (and, optionally, also in the initial RAM filesystem)

5. Blacklist rtsx mmc modules via kernel parameters.

6. If wanted/needed, update the initramfs.

7. Reboot, and check to see if the card reader works.
