CompactFlash Card Reader - 2.6.4rc3

[matthurne]

I just need some help getting this dang flash card reader working again. Its a PNY CompactFlash reader. It worked under 2.4...as /dev/sda. Well since upgrading to 2.6 all I get is /dev/sg0 for it. Yesterday I got udev working, and have the newest sysfsutils, hotplug scripts, etc. Udev and sysfs do a great job of creating/removing sg0 when I connect and disconnect the reader, but no sda. I can't mount sg0. Here's what I get when I connect the reader, I enabled verbose output for USB Mass Storage in the kernel...

Notice the printer, which works fine through /dev/lp0 as udev set it up...so it seems USB in general is fine as well as udev. Something with the USB Mass Storage drivers perhaps? *shrug* Let me know if you can help and/or if you need any more information.

Well after weeks of trying to fix this problem, I finally got it worked out. I use Slackware...on boot I had it load the usb modules and scsi modules. Well, I had it loading sg (scsi generic) but not sd_mod (scsi disk). So I loaded sd_mod, unplugged the card reader and plugged it back in, and beautiful udev slapped sda and sda1 into my dev directory and everything works.

Yay. :-D
