Realtek card reader not recognized

Questions about problems with your hardware. For example, if you the kernel hangs during boot because of an hardware failure or if you have a problem with a driver not working or missing.

Realtek card reader not recognized

Postby xerces8 » 18 Jan 2015, 20:43

Hi!

I installed v4.4.1 to an SD card (from Windows, then from Linux, with same results).

After booting, it can not find the SD card. (so it does not finish loading)
I also booted it from an USB stick, and tried to Access the card reader from there, also without success.
I tried 32 and 64 bit kernels, the standard and the alter, but they fail to see the SD card.

The reader is from Realtek, with USB ID values of:
USB\VID_0BDA&PID_0129&REV_3960

It works in Ubuntu 12.04.04 LTS (kernel 3.11.0), 14.4 64 bit (kernel 3.13.0) or RIPLinux 13.7 (kernel 3.2.1)

Any idea?

It does not work with Ubuntu 14.10 either (kernel 3.16.0).

So maybe it is a regression in the kernel itself.

This turns out to be not true. At least in 64 bit version the reader works. (the first test I did was maybe 32 bit)

It seems the culprit is the rts5139 kernel module. It is/was in the staging area and not built for the distros that I mentioned to not work with the reader.

The Ubuntu 14.10 (x64) does not have it either, but uses the rtsx_usb* modules.

Maybe the next release of SystemRescueCD will have this?

To clarify:
in kernel v3.15 the staging driver rts5139 was removed and the new rtsx_usb (config MFD_RTSX_USB) driver was added.
