Yes, the Hyper-V keyboard driver does exist in Trusty. Trusty has the two upstream commits:

c3c4d99485ea51cd354ed3cd955a8310703456b6 Input: hyperv-keyboard - pass through 0xE1 prefix
aed06b9cfcabf8644ac5f6f108c0b3d01522f88b Input: add a driver to support Hyper-V synthetic keyboard

Do you happen to know if this issue just start happening after a recent update or upgrade? Also, does this issue also happen if you boot the latest mainline kernel, which is v3.14-rc4? It can be downloaded from:
