Is syncronizing 2 isochronous signals possible on 2 different hubs? on
the same hub? I need to make sure that data from 1 USB port and data
from a different USB port arrive at my circuit at the same time (to
within 1us). For now I am only using Full Speed.
thanks

? Are these numbers the same on two different
root hubs?

According to one Cypress document the FX2 averages 39MB/s in XP (so
9MB/s faster than I am getting on Linux, but still under the 50MB/s
claim). The important thing for me is that I can write to disk using
iso at 24MB/s.

%
ISO OUT=23.975MB/s [23.975] CPU=5%
I am surprised that the BULK IN did not compare with the FX2 document. I was
hoping for that 40MB/s, and that does not even including writing (although
there is enough CPU ).
thanks for your advice on this!

So, basically make threads for both read and write?
thanks

I guess using read and write threads is one possibility of many then...

I want to report my progress with the ovfx2 driver and the Aplux MU2-35.
I applied the patch Mark McClelland sent me for 2.4.23 on a MDK9.2.
I made a program that opens and reads from /dev/video0 that is more simple
than xawtv. In xawtv I see the camera light blinking (frames are being
read) but

The ovfx driver for some cameras uses the FX2 bulk mode, and a person
names Vladimir at http://volodya-project.sourceforge.net/overview.php
has done a large amount of development for the chip. The chip is great
and I have some code at http://tedhuntington.us/software.htm.
