> So, queing alot URBs is the recommended way to sustain the bus? Allowing > way bigger buffers will not be realistic? usbfs could copy the user buffer to a bunch of non-contiguous pages, and then fire those off in an urb using the scatter-gather stuff. [Rather than, as now, allocating a bunch of contiguous pages using kmalloc]. That would probably make it possible to use much much bigger user-space buffers. Plus the code looks rather easy to write.
