I see they're still way behind the game in the UK, we've had it here for

It is working, in the sense that it doesn't crash and it happily sends
and receives packets. But it's slow - slower than bulk! In my tests I
could get only a bit less than 4 Mbaud with bulk, and a bit less than
that with iso. However no-one else has yet been able to confirm similar
speeds, so for all I know it might be an issue with my ISP. But most
likely there is a bottleneck in the driver. I've been meaning to look
into this for ages, but didn't have the time.

I will try it out.
