Looks like the "ub" module is setting /dev/uba or /dev/ub/a to be your
device names.  But googling shows you don't want to use /dev/uba because
it's slow, and I'm guessing /dev/ub/a is just an alias for /dev/uba or
vice versa.

Google shows, though, the "ub" kernel module conflicts with "usb-storage",
so it looks like you want to disable "ub" somehow and use "usb-storage"
instead.  Maybe try moving "ub.o" somewhere the kernel can't find it and
re-run `depmod -a`?

Hopefully someone with more experience in this will jump in the thread.
Good luck!
