Hi,
I was browsing through the USB Programming Guide at usb.cs.tum.edu, and I
was wondering about one thing... I came across usb_control_msg(), and I
recall reading on linux-usb-devel@ that it is not safe to call this function
from interrupt context (e.g. probe() and handler functions), because it may
sleep (but I could be wrong).
Maybe it�s worthwhile to mention explicitly whether or not this is allowed,
so new device driver writers won�t fall into the trap of initializing their
device while in probe().
NB: is there a particular reason that example code is displayed as an image,
and not simply as <pre></pre> in HTML?
