SD Card problems #4
Description
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.
