sd card reader not working

[Guest]

Hi,

I am facing an issue with my HP pavilion dv2224ea laptop with Vista home
premium. It has a built in card reader which worked fine initially.But now it
has stopped recognizing any SD cards. My Sd card shows up under "Disk drives"
in Device manager with a yellow exclamation mark next to it. And also when I
right click on it and go to Properties, it shows " This device can not start
(code 10).

I have tried updating drivers but to no avail .The HP tech support guy
asked me to download the latest updates for the BIOS and the card reader.
That didnt work either. Any suggestions please on what I could try to fix
this isue?

Thanks,

In Device Manager, right-click on the device and select "Uninstall",
then restart your computer. This procedure should reinstall the device
properly.

Thnaks Carey but I have already tried unistalling the drivers, updating them
etc etc. But it didnt help.

I have requested the hotfix. So will wait and see whether that works.

Thanks,

Hi Rupa,

First thing you want to do is to determine which bus your SD card connects
to. In the device manger, choose View\Device By Connection and look at the
Device Type and the Driver(in properties page) of your SD card's parent
node:
If it is USB device, it usually uses MS USB mass storage driver
(usbstor.sys).
If it is SD host adapter device, it usually uses MS SD bus driver
(sdbus.sys).
If it is other type of device, you are probably using a non-standard
device with third-party driver.

The hotfix in Car's email is only for USB card readers. There is another
hotfix for SD host controller driver: http://support.microsoft.com/kb/933847

Thanks,

Hi Yue,

Thanks. I checked that and it uses the sdbus.sys. Regarding the hotfix you
mentioned, I had tried to install it earlier when I noticed this issue. But
it keeps saying that this update does not apply to my system. Any thoughts on
that please??

Thanks,
Rupa
