I own a Line6 GuitarPort and I am trying to get it to work with this driver. First off, are there any reports of this working with the GuitarPort? Is this a hopeless endeavor?
I pulled down the latest source (0.7.3beta) from svn and tried to edit the specified device id arrays, but I don't quite know what I am doing. I have very limited experience programming in C so forgive my noobness and any help would be much appreciated.
After plugging in the GuitarPort my output of "lsusb -d 0e41:" is:
Bus 001 Device 005: ID 0e41:4750 Line6, Inc. GuitarPort
But I am not sure what I am supposed to do with it. After looking through driver.c, I didn't see any obvious place to put the 4750 device_id.
This is the output I get when I try to make install after those changes (obviously, I am doing something wrong):
make -C /lib/modules/2.6.22-14-generic/build SUBDIRS=/home/decappa/Desktop/svnline6usb/trunk modules

Hopefully someone out there can help me. I have looked around a bit and have found a few users who would appreciate a Linux driver for guitarport. I hope I can contribute something meaningful to this project.

I'm not a c programmer but I have a fair amount of programming experience, and as you helped me out, I thought I'd take a look at this one. I've opened the source on KDevelop and then I did a search for LINE6_DEVID_BASSPODXTLIVE (just picked an existing device). The IDE found 8 matches, the most interesting being in usbdefs.h. I think you need to define your constant (LINE6_DEVID_GUITARPORT) here and it gets replaced with your device id (0x4750 I guess) during compilation.
Then I think you'll have to add the LINE6_DEVID_GUITARPORT constant to the 5 switch statements in driver.c (near lines 361, 586, 603, 715 and 788 ) and also midi.c (near line 168).
I hope this all helps, and good luck.

As far as I know, GuitarPort is strictly a none-midi device, so all the places where Toneport should be just fine, though I am still working on getting my Toneport UX2 to be recognised by my PC with no errors...
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The GuitarPort and TonePort seem to use a different protocol for audio data transmission. A user once sent me a log file, which looked quite different from what travels over the USB to a POD device. So I see little hope for Guitar-/TonePort support unless a user with USB driver development experience addresses this issue. I could give it a try myself (would certainly be interesting), but I don't have such a device.
Kind regards,
Markus

I too would like support for the GuitarPort. I have one and it is one of the biggest reasons I haven't converted fully to Linux. If I can help in anyway to get the support, please tell me. I have no coding experience but I do have the desire to help.

That said, this is what I *have* done so far:
device.c:
...
/* table of devices that work with this driver */
static struct usb_device_id line6_id_table [] = {
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_BASSPODXT) },

{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_PODXTLIVE) },
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_PODXTPRO) },
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_POCKETPOD) },
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_VARIAX) },
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_TONEPORT_UX1) },
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_TONEPORT_UX2) },
{ USB_DEVICE(LINE6_VENDOR_ID, LINE6_DEVID_GUITARPORT) }, // My edit to add GuitarPort
{ },
};
MODULE_DEVICE_TABLE (usb, line6_id_table);
static const char *line6_name_table[] = {
"BassPODxt",
"BassPODxt Live",
"BassPODxt Pro",
"PODxt",
"PODxt Live",
"PODxt Pro",
"Pocket POD",
"Variax Workbench",
"TonePort UX1",
"TonePort UX2",
"GuitarPort", // Another edit.
0
};
...

Hi Douglas
