I'm not really a kernel hacker but have fixed drivers that wouldn't compile
with a newer kernel. It seems from a quick online search of what people
did to fix other drivers the problem lines may be safely deleted.  Try
at your own risk.

If you can't get that adapter working I am using a Rosewill RCW601 which is
the Prolific PL2303 USB to serial adaptor driver in kernel.org kernels.  Now 
using 2.6.18.2 but also used 2.6.15.4
