Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

So, I have to reboot the computer in order to recover the normal automount behaviour. When I first installed this device it was recognized by the kernel as a remote controller. To get it working as a multi-card reader I had to blacklist mceusb driver. ~~~~~~~~~~~~~~ Aditional info ~~~~~~~~~~~~~~ Ubuntu version: 12.04.3 Kernel: Linux 3.2.0-55-generic #85-Ubuntu SMP Wed Oct 2 12:29:27 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Card reader (commercial name): CoolBox CR-600 lsusb: Bus 001 Device 003: ID 0bda:0161 Realtek Semiconductor Corp.
