Description of problem:
I have a HP laptop (hp pavilion ze4315us) with usb1.1. I am
attempting to use the Lexar USB2.0 Multi-Card Reader with FC3. It
works perfectly file in windows xp... but when tring it in linux all I
get is the following message in /var/log/messages:
Dec 22 11:45:04 localhost kernel: ohci_hcd 0000:00:02.0: wakeup

Dec 22 11:45:26 localhost 05-pam_console.dev: Restoring console

The device is never mounted and when I try to manually try to mount
'/dev/sda' manually all I get is the error message:
mount: No medium found
I have heard of ther people's sucess with this device on linux... But
it doesn't work at all for me.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. plug the device into the usb port
2. watch /var/log/messages
Expected Results: the device to mount...
does this device have partitions on it?
# fdisk -l /dev/sda
to let the kernel reread all partitions use:
# sfdisk -R /dev/sda
'fdisk -l /dev/sda' returns with nothing (I assume that means there
are no partitions?)
and when I execute 'sfdisk -R /dev/sda' it returns:
/dev/sda: No medium found
sfdisk: cannot open /dev/sda for reading
I know there are directories and pictures on the CF card... I put them
there in hopes of downloading them from the reader...
reassigning to kernel
added to whitelist, in the next kernel update you should see all the slots show
up as sda1, sda2 etc..
In the meantime, you can work around this by loading scsi_mod with the
max_luns=N argument (where N = number of slots)
options scsi_mod max_luns=8
to your /etc/modprobe.conf, and then next time it gets loaded the devices should
added to whitelist in todays update.
