Hi Bob,

I've download the kernel source and added the idProduct and idVendor to 
the pl2303 (both .c and .h files).
I have no experience in rebuilding the kernel. I don't know the save 
step-by-step rebuilding the kernel.
I am trying to find some information from search engine and the ubuntu 
user mailing list but still confuse to do that.

Can you give me a save step-by-step (from your experience of course) to 
rebuilding the kernel.
Mine is 2.6.12-10-386 kernel on Ubuntu 5.10

Regards,
Andria
