Hello Alan,
First off, thanks for the response and sorry for the delay here.. very
busy here!
The problem is caused by the ehci-hcd driver's not-so-great support
for scheduling periodic transfers to full-speed devices. That's why
the HP and Dell systems have no trouble but your Gateway laptop can't
handle it.
There are various reports that the Windows driver has an option to FORCE
this X-Fi device to use USB high speed which solves some specific sound
quality issues, etc. but I have not seen anything about needing that
switch to support 96khz at. There was a similar trick done on the
Audigy2 NX card and I'd be willing to try some code that could force the
device to high speed that but it's unclear what's needed for the X-Fi card.
Audigy 2 NX required a hack to go into highspeed mode

I've also researched around where some people recommended to remove the
EHCI module to use the OHCI but that doesn't seem to work on this
specific laptop's chipset.
To be clear, I'm ONLY looking to record two channel (stereo) from this
sound card's line-in. I'm more than happy to disable any playback, etc.
if that might allow this USB device to stay under the Full speed
bandwidth limit
You can provide some more details: The output from "lsusb -v" for the
sound card, and a usbmon trace showing the RECORD failure (see
Documentation/usb/usbmon.txt for instructions).
Absolutely. Please see here:
