The code has sat around for a long time because when I first posted the patch 
I got no feedback to indicate if anyone else was suffering from the bug and if 
anyone else had hardware that exhibited the bug it was supposed to fix so I 
didn't want to pursue submitting it. Over the years I have seen occasional 
reports of users suffering from the problem but I no longer have any EPP 
hardware to test it on.

That's why I posted the mail that said if someone else can verify the patch is 
still useful I'm happy for it to be submitted with my signed off by on it (and 
the original mail did use an @ sign, the word at got added by an email 
obfuscator in a mailing list archive along the way.)
