Yeah, it sucks.

> This adds ~1ms latency per transfer cycle for rapid bidirectional communication which leads to half the USB 1.1 speed for smaller packets at best.

Still, I don't think this patch should be applied /for everyone/. Maybe compile out-of-tree and load as a kernel module, if possible?

The patch removes this latency and improves transfer speed, without any drawbacks.

I still have a MB with just a USB 1.1 controller. I would hate it if the USB stopped working after this fix. I think a config option for the delay would be best.
