Hi Dan,
Thanks for your advice. :)
Did you know Chinese?
My system was an embeded system using Admtek 5120P CPU, and running on linux
kernel 2.4.18
the CPU built-in a USB controler.
form you advice, I found the code at printer.c. but I don't have any idea
abut usblp_bulk even the error code.
did you have any idea why my system happen this error?
PS:
Since I am a freshman on linux system, is there any document describe usb
driver and usblp driver?
Thanks for your kindly help.
-Sam
