Printer MP6150 driver installed itself upon plugging in the printer. Printer is recognized (lsusb shows it) but does not mount. If the printer is recognized, the driver must be working (or?), but something is blocking the system from mounting the printer. Tried the usual things: power of printer, restart Ubuntu etc.

Listed below result of lsusb and fstab:

Here is what I have tried:

• Tried the HK link again, but no luck so far. However, I connected the printer wirelessly to router on other xp box.
• Installing the driver from ppa:michael-gruz/canon doesn't work, but the driver is installed
