problems in E100bex sample code

I am using E100bex miniport driver sample code from the DDK to build my
driver for a PC card. I am facing some problem in the Transmission of data
from the host to the card. The results of “bug bash” contest on this site
shows that some one reported that there are problems in buffer allocation
in "e100bex " sample driver code. I would like to know what those problems
If some one knows more abt it, please let me know.

thanks and regards
