broadcom BCM57765/57785 sd card slot not working

**mabtifro2** · October 2nd, 2013

didnt work in 12.10, didnt work in 13.04, and still not working in my beta 13.10. my computer is an acer v5-171. sometimes it used to work if the sd card was already inserted on start up. but not its doesnt seem to work ever. in fact, since upgrading to 13.10, the computer doesnt even shut down if there is an sd card in the slot on shut down, it gives me some error till i remove the card, then it shuts down fine. is there any hope???

Same issue here. Running 12.04, and the sd card reader does not recognize the card.

Looking at syslog does not reveal much:

Nov 2 18:59:03 Ubuntu kernel: [ 7282.848244] sdhci: Switching to 1.8V signalling voltage failed, retrying with S18R set to 0

And the card reader should be capable of detecting the SDHC, looking at the details:

From: lspci -v:

In addition, the SD card can be read without issue from a USB port, using an external card reader.

I've tried 3 different SD cards, of varying sizes / cabablilities, but so far, have not been able to get Ubuntu to recognize any of them.

Any helpful pointers..?
