Have you checked your BlackBerry to make sure that the SD card is being shown? Options -> Media Card -> Mass Storage Mode Support: On
Your first entry (again, stop with the btool junk - that is confusing you and getting in the way) shows that the device is being plugged in but not "showing" the SD card to the PC. Here's how it's supposed to look - notice my first two lines are the same as yours but then are followed by the SD card:

... etc. more junk ...
The fact that you're not seeing that info like mine points to the device not "showing" the SD card to the PC, or your PC not loading the proper usb_storage module.
If you plug it in, then as root run 'modprobe usb_storage' - does it work?
