Unfortunately, it didn't - I'm still getting timeouts with 2.6.10. BTW,
this is 2.6.10 _without_ the msleep(10) in core/message.c::
usb_internal_control_msg(), that we experimented with earlier.
I think that's what you wanted.
I've attached some dmesg and /sys/.../usb1/registers snapshots I took
after the system had booted and whilst the hub was failing to attach. Hope
these help
