[Line6linux-devel] A start on supporting the POD X3 Live

[Boyd T. <bti...@gm...>]

Before hacking away at the driver to support my new X3 Live, I plugged
it in with USB and just watched /var/log/messages.  Here's what I got:

Oct 16 20:17:48 bht-lenovo kernel: usb 5-5: new high speed USB device

Looks like the product ID is: 0x414b

Does anyone have the bean-shaped X3 to see what it's device ID is?

Attached is a patch file for current SVN Trunk.  It's a start at
adding support for the X3 products to the driver.  Seeing as I don't
exactly know what I'm doing, it's not really working yet.
/var/log/messages now spits this out:

So, I'm wondering what the next steps are.  Does anyone have
recommendations on what I can do to fix up the driver?

Thanks,
