I have no explanation - the output you posted suggests that the driver
is not matching the device you plugged in.  Therefore you don't get
the "Line6 POD HD300 found" message that you normally see at the very
beginning when the device is detected.

I suggest you do the following to further debug what is going on:

Please check that you have the following line in /lib/modules/$(uname
-r)/modules.alias:
alias usb:v0E41p5057d*dc*dsc*dp*ic*isc*ip*in* line6usb

This is normally automatically added when you install the kernel
module.  It's how the system knows to load the line6usb driver when
you plug in the POD HD300.

Once you're sure the modules.alias line is there, restart your
computer and don't manually modprobe the driver.  When you plug in the
POD the driver should be automatically loaded - you can check with
lsmod | grep line6usb.

Now check dmesg and see if there is a "Line6 POD HD300 found" message
or anything else about line6 or the USB device.

If the module is being loaded but you're getting no dmesg logs about
it, double-check that your dmesg log level allows dev_info() messages
through (please search for how to do this, I can't remember).  Then
the next step would be to add a printk() to
drivers/staging/line6/driver.c:line6_probe() so we know the kernel is
asking the line6 driver to try the new device.
