CUPS & strange USB printers problem

[juice]

Look at this:
- I,ve got 2 usb printers connected:
     crw-rw----  1 root 180, 1 sty  1  1970 lp1
     crw-rw----  1 root 180, 0 sty  1  1970 lp0
- but something is weird, when I try to localize, which is which:Oct 23 12:08:40 [kernel] usb 1-1: new full speed USB device using address 5

BOTH ARE CONNECTED AS /dev/usb/lp0!!
