usb-slot-specific mountpoint

[toneman77]

Hello everybody

I'm trying to always mount (block) devices to a specific mountpoint, like
all block devices in the left usb slot go to /mnt/left and all in the right slot to /mnt/right.

I think I have to do some udev trickery but don't know where to start.
Anyone got an idea?

any help appreciated
