In this case, I don't have anything to mount. But udev doesn't know that. As far as udev can tell, you might want to mount /dev/sdc. > > > Is there some sample application which talks directly to usb-storage module > > (to have an idea how to do it by myself) ? > > > > There's no way talk directly to usb-storage.

They have headers with USBC and USBS respectively. Everything sent to the target has to be packed in mass-storage packets; otherwise the target wouldn't understand it. You probably want to use the SG_IO ioctl. Or maybe you want to use the SCSI-Generic API, see: http://www.linux.org/docs/ldp/howto/SCSI-Generic-HOWTO/index.html > Another idea is that the debugging symbols are "written" into the virtual partition (maybe somewhere to the part where I/O errors are generated) - and debugger hardware interprets and executes them. But I am not sure about that either. I don't understand what you mean.
