Re: epic100 error

[Stefan Jaschke]

Hi,
it seems the epic100 driver broke between 2.4.2 and 2.4.3.
I reloaded the epic100 module with the parameter "debug=6".
Unfortunately, I cannot make much out of the log:

I also noted that there are substantial differences between the original epic100.c at
http://www.scyld.com/network/epic100.html and the version included with 2.4.3.
Who did these changes?
