The instructions in your manual are out-of-date. In 2.6.0 and the more recent 2.4 kernels you don't need to add that entry to unusual_devs.h. > i'm getting > this output in dmesg: > > usb-storage: This device (09bc,0003,0001 S 06 P 50) has unneeded > SubClass and Protocol entries in unusual_devs.h > Please send a copy of this message to > <[EMAIL PROTECTED]> That's just an indication that the entry you added wasn't needed. > Even more problematic though is that everytime i reconnect the device to > the computer, the SCSI subsystem "creates" a new host (sorry if that's > technically incorrect, i don't know anything about how this internally > works). > At first plugin i can access the CF card in the device it trough > "/dev/scsi/host0/bus0/target0/lun0/part1", when I unplug and replug it, > i have to use "/dev/scsi/host1/bus0/target0/lun0/part1", etc. That's how the SCSI system works now.

The answer is to use a hotplug script to mount the card (or to set up the proper device links so that your fstab will work).
