1.Memory-stick When a memory-stick is plugged in, a link to the device and the device-partition is generated (e.g. /dev/@sda,/dev/@sda1) - o.k. When it is then unplugged and a mount command for the /dev/sda1 is sent, the partition-link is erased; when it is plugged in again, no partition link (/dev/@sda1) is generated anymore. 2. Card-reader A link to a device partition is only generated, when the card-reader with a card in it is plugged in at boot time. Reproducible: Always Steps to Reproduce: 1.boot the computer 2.do as described in 'Details' 3. Actual Results: described in 'Details' Expected Results: 1. A partition device should be generated on plugging in - independently how many correct or incorrect mount commands were sent. 2. The same behaviour should be valid for the card-reader I use a motherboard ASUS P4B533 and built a gentoo 2004.2 system from stage3
Can you reproduce this issue with a vanilla 2.4 or 2.6 kernel?
I tried it with kernel vanilla-2.4.27; the behaviour remains the same
In that case its an upstream bug, not much we can do, please report it to linux-usb-devel@lists.sourceforge.net - I suggest posting kernel logs with USB debugging messages enabled. I'd also suggest trying 2.6 which seems to handle USB devices better.
