Are you sure that HID modules are loaded at the time you are being asked 
for the dmcrypt password?

In the provided dmesg, I can see

[   17.106371] usb 2-1.2: New USB device found, idVendor=413c, idProduct=2106
[   17.106376] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[   17.106380] usb 2-1.2: Product: Dell QuietKey Keyboard

[   17.115713] input: Dell Dell QuietKey Keyboard as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/input/input11
[   17.115968] hid-generic 0003:413C:2106.0002: input,hidraw1: USB HID v1.10 Keyboard [Dell Dell QuietKey Keyboard] onusb-0000:00:1d.0-1.2/input0

i.e. the keyboard gets properly autodeteted, but I have no idea whether 
this was before or after dm-crypt password prompt.
