The u: devalias only applies to USB 2.0 mass storage devices.  disk: 
applies to either USB 1.1 or USB 2.0 mass storage devices, whichever is 
present.

USB keyboards are almost always USB 1.1 devices.

I wonder if your USB stick is a USB 1.1 device, or perhaps it is plugged 
into a USB 1.1 hub, or perhaps the presence of the keyboard is causing 
the stick to be detected in USB 1.1 mode.

I don't have a fully-formed explanation for your problems, but those are 
my preliminary thoughts.
