Subject: Creative X-Fi USB 5.1 Driver
Date: Tue, 3 Feb 2009 20:36:15 -0800 (PST)	[thread overview]
Message-ID: <531396.7445.qm@web35601.mail.mud.yahoo.com> (raw)

Hello,

I was reading the USB Audio Specs from http://www.usb.org/developers/devclass_docs
The document talks about Effect Unit Descriptors and few other descriptors.There is no mention of such descriptors in the &#39;lsusb -v&#39; output for the USB X-Fi 5.1
Does this mean thet the X-Fi,Crystalizer features of the USB X-Fi are implemented purely in software?
Here is a link to the lsusb output http://mndar.phpnet.us/usbxfi/files/creative.txt

The document &quot;Audio20 final.pdf&quot; also mentions that bDeviceClass, bDeviceSubClass and bDeviceProtocol should have values 0xEF, 0x02, and 0x01 respectively but in the &#39;lsusb -v&#39; output all three values are 0. Any idea why it is so?

Regards
Mandar Joshi
