A change in Linux Kernel USB api - 2.6.12 kernel
Hello,
Haven't post a blog here for a while; Sorry ; there was some pressure at
work.
There is a little change in Linux Kernel USB api from 2.6.12 kernel.
In 2 USB methods:
usb_bulk_msg() and usb_control_msg(),
The timeout parameter value is changed to milliseconds.
(It was in jiffies in prior kernels).
Notice that the timeout is in both cases an int,
so the compiler will not shout if you are using
usb drivers which were not fixed according to this
change.
What will happen if you **DO** try to use such
an unpatched drivers ? well , maybe you can
tell me?
Cheers,
USBLOG
