Ubuntu 9.10 and Alcor Micro Corp. 8-in-1 Media Card Reader

2010-03-20 Update: In Ubuntu, the below documentation seemed to have been the path to take for fixing the SD Card Reader's failing to automount an SD card more than once, however, the trick is not to use the "Safely Remove" Option in the right click menu of the icon's device.

I repeat, if you are having SD Card issues, which I'm probably by myself in this matter, reboot and thereafter refrain from using the "Safely Remove" option.

"Eject" or "Unmount" options work fine.


Original:

Inserting an SD Card works flawlessly 1 time, unless the system is rebooted and then the reader works again, but only once per reboot. After the reader is automounted and files appear in the filemanager, if you "SAFELY REMOVE" or "EJECT" the drive, the command lsusb shows no entry for the usb device until rebooted. My guess is the module running the device crashes in the "safely remove" process.

The fix:

In a terminal window

sudo nano /etc/modules

In the nano editor, use the arrow keys to move the curser to the bottom where there is a clean line under the others. Add this line

usb_storage

Then save by hitting CTRL-X, hit "Y" key for save, and hit ENTER to write to /etc/modules.

Then run:

sudo reboot

I'm still not sure if adding this module to the modules file will fix the issue. It seems that the reader breaks when right clicking and selecting "Safely Remove". If you right click and use "Unmount" or "Eject", the reader's driver continues to function. For now, I will advize not using the "Safely Remove" option as it fails to work further 100% of the time. Use the other of the two options to remove the drive: Unmount or Eject.
