Hi David,
I thought my post got lost; I never saw it appear and hadn't seen

At this point, the actual ISO transfer machinery all looks perfectly

Here are some more small USB fixes for 2.6.17-rc3. They contain a few
small bug fixes and a few new device ids for new devices.
All of these changes have been in the -mm tree for a number of weeks.

In kernel 2.6.16, if a mounted storage device is removed, an oops happens

Because of the way stringify works, using an expression
like 64 * 1024 for UDSL_MAX_BUF_SIZE results in 64 * 1024

65536 directly (this was the only way I found of fixing this).

Hello Allan,
Thanks for your answers. Just one question, when we use the URB_NO_INTERRUPT

it inhbit all the interrupts? If it inhibits all the interrupts how can we
monitor the status?
