So the total length may be in 'urb->actual_length', but the actual data in the buffer may not be contiguous, because it's created from multiple smaller frames, some of which might not be full length? I dunno. That would explain the problem - actual_length is correct, but the 'copy_to_user()' still doesn't copy all the data, because it's fragmented.
