Well, after dealing with this a little I remembered that mceusb was in the blacklist to get reading Smart Cards with this device. So, the module has nothing to do with USB keys or SD cards. In fact, now I can safely re-enable it without losing Smart Card functionalities.
Better yet, I've managed to resolve the "bug" and it's easy to reproduce. 1) Insert an microSD or whatever card you have. 2) Once it's detected and automounted, right click the icon on Unity launcher and two options will appear. One is for safely removing the "drive" (the card) and the other just "unplugs" the device, because on its own for Ubuntu looks like a removable media since it is hooked to an internal USB port. In my opinion these two options could mislead the average user. Until now I was thinking they both serve for the same when the reality is that one is almost useless. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1249134 Title: 0bda:016 Request mceusb blacklist for CoolBox CR-600 Status in “linux” package in Ubuntu: Incomplete Bug description: When I first plugged the CoolBox CR-600 in to USB it is recognized by the kernel as a remote controller with driver mceusb.
