The usb-ohci driver, widely used on non-x86 platforms, has hit
the same issue. (Including on some ARM setups.) An EHCI driver
(usb 2.0, 60 MByte/sec) under way has it too.

So this mean if I do:
write(10*MSS)
write(1)
write(1)
2.4 can send 10 packet with MSS large payload plus two packets w

It makes. One small packet is allowed to fly, not depending on packets_out.
