Apollo stops talking from time to time

[Michael Whapples]

Hello,
I have noticed that my apollo seems to stop talking from time to time. 
The last time this happened I looked at the output from dmesg and found 
a message saying:
Apollo: too many timeouts, deactivating speakup

I am using GRML with speakup built from the source debian package Samuel 
recently made. What's causing this and how might I solve it?
