Doable today, by simply applying some limit and if we hit it schedule a timer to continue later. uhci emulation does this, but it's basically no extra work there as usb emulation is timer based _anyway_. > That's too big a can of worms for > this patch, though.

Agree, given the use case this isn't critical by any means. cheers, Gerd
