Description Kalin KOZHUHAROV 2005-09-14 21:33:56 UTC 
I was trying to get more persistent mapping for my CF cards on my laptop.

Reproducible: Always
Steps to Reproduce:
1. Plug in a CF memory card
2. ls -l /dev/disk


Actual Results:  
not linked, although accesible via /dev/hde*

Expected Results:  
link it under the various categories.

Runnig stock udev-0.68 on almost vanilla-2.6.12.2 (about to upgrade).

: After plugging in:

Comment 1 Greg Kroah-Hartman (RETIRED) gentoo-dev 2005-12-07 13:19:10 UTC 
cf memory cards can't show up in /dev/disk/ until the kernel is changed
to properly handle hotplug events with these devices.

Hopefully upstream will work on this soon.

So, until then, udev can't do this, sorry.
