Yes, it worked for 10.2 (and I think for 10.1, 10.0 too)

Even more: it worked till yesterday with beta2 too (before last reboot).

Here is the strace:

# strace /usr/share/cups/lib/backend/usb
[...]
open("/dev/usblp0", O_RDWR|O_EXCL|O_LARGEFILE) = 3
ioctl(3, SNDCTL_DSP_SYNC, 0xbfeca774)   = -1 EIO (Input/output error)
close(3)                                = 0
open("/dev/usblp1", O_RDWR|O_EXCL|O_LARGEFILE) = -1 ENOENT (No such file or
directory)


I noticed a short delay in strace when /dev/usblp0 got scanned. I don't know if
this is related?
