SD Card problems

[stevelord]

Hi,
I'm having some interesting issues with Micro-SD support. Wondering if anyone else has had the same thing or knows what's going on.

When I use a Micro-SD card I can see it on boot and mount it fine, I can even list files and directories, and I can query the usb SD controller via lsusb. When I try to access the files after a small amount of access, the USB device appears to disconnect. Here's the output of logread from doing a cat of a file on the Micro-SD:

root@OpenWrt:/# logread -f

Does anyone know what's happening? The drive and USB SD card reader are no longer visible in lsusb after this happens, so it looks like the USB SD card reader is being disconnected.

What do you have as far as lsmod?

I have 2 zsuns running openwrt. One of them is unable to read the sdcard. I am not sure how to fix the issue. Cant figure out if it is a bug or a hardware issue. Did anyone figure anything out?
