That's possible but it's not necessarily the case. There is one real
bug in the hid-input.c which would cause a hang on single-CPU machines
when connecting the BTC keyboard. See this mail (patch included):

There also seems to be a bug in the BTC keyboard which causes the
hid-core to time out when initializing the keyboard. That problem
isn't fatal, but it's annoying to have to wait for 10+ seconds to wait
for the keyboard to become online. A workaround for this bug can be
found in this mail:

I'd be interested in hearing if that fixes the problems for your machine.
