Regarding a pause after hub_port_reset() to allow a device some time to
get ready, I applied the following patch suggested by Alan Stern:
--- drivers/usb/core/hub.c.orig 2005-10-27 20:02:08.000000000 -0400
+++ drivers/usb/core/hub.c 2005-11-08 17:49:56.000000000 -0500

/* Reset the device; full speed may morph to high speed */
retval = hub_port_reset(hub, port1, udev, delay);
+ msleep(1000);
if (retval < 0) /* error or disconnect */
goto fail;
/* success, speed is known */
This makes my iPod work with USB2 on Linux 2.6.14 (vanilla).
My USB2 flash drive still doesn't work, but I'm thinking it never even
gets this far in the code from the debug output. At least, my kernel
debug messages never showed up when it was plugged in anyway.
Note: I have not yet tried this more than half dozen times, but so far
it has worked every time.
