That's because it is not listed in "/usr/share/usb.ids" (the file might be 
elsewhere under your Linux distribution, the original is maintained at 
http://www.linux-usb.org/usb.ids). I just noticed that the list is rather 
incomplete, I will start a request to collect the missing information in a 
separate message.

Where did you search? In case you searched in 
"https://line6linux.svn.sourceforge.net/svnroot/line6linux", then 
"driver/trunk/driver.c" is the most recent one. The version in 
"driver/branches/ux2" might also be relevant for you, but is currently quite 
experimental.

Unless the KB37 turns out to have an almost identical interface as another 
device supported by the driver, it is very hard to add support for it. The 
easiest way to find out is to just replace the id of a device you believe the 
KB37 could be similar to (e.g., the UX1) by the KB37 id (0x4152) in 
"usbdefs.h". The driver will then believe that the KB37 is actually a UX1 and 
try to communicate with it like with a UX1. The result could be anything 
between working, not working, and crashing your computer. If it's not working 
(or crashing), more effort is required to get the KB37 supported.

There is one useful piece of information which you can easily produce, namely 
the output of the command "lsusb -v -d 0e41:" (executed as root), can you 
please send this to me?
