Fair argument. I haven't actually tried sending a big urb through
USBDEVFS_CONTROL but I noticed that MAX_USBFS_BUFFER_SIZE is not checked
in that codepath. I wonder if something else in the chain will reject
big control urbs.
But you did want it for something, didn't you?
Not exactly. I am writing a userspace USB I/O library (like libusb), and
during testing I realised that I could not submit a bulk URB for ~110kb
of data. While implementing the code to divide the request into several
URBs, the thought "I wonder how this works for control URBs" crossed my
mind. That's all :)
I published the source of my library yesterday:
