<p>Thanks so much, Shijun! Your solution worked perfectly. <br>
</p>
<p><br>
</p>
<p>Just to put it out there, here are the contents of drivers/media/usb/as102/as102_usb_drv.c from lines 116 to lines 119:
<br>
</p>
<p><br>
</p>
<p></p>
<div> #ifdef TRACE<br>
dev_dbg(&bus_adap->usb_dev->dev,<br>
"want to read: %d bytes\n", recv_buf_len);<br>
#endif</div>
<br>
<p></p>
and lines 134 to 137: <br>
<br>
<div> #ifdef TRACE<br>
dev_dbg(&bus_adap->usb_dev->dev,<br>
"read %d bytes\n", recv_buf_len);<br>
#endif</div>
<br>
The two address of operators at the front of bus_adap were missing from the original file, and their addition fixed the make modules compilation error.
<br>
<br>
Thanks, again! - Nick <br>

<div>Also, there is no need for you to install that kernel by you own. You can download the virtualbox img directly.</div>

<p>Forgive my questions if they are elementary or naive. I am a bit out of my depth with Linux Kernel instillation, but I very much desire to learn.
<br>
</p>
<p><br>
</p>
<p>I have cloned into the github source repo. I have not tried to patch against my previously downloaded 4.1.32 Linux kernel source code, as I believe the Litmus source is a complete kernel source code if cloned from the source repo? Please correct me if I
am mistaken. <br>
</p>
<p><br>
</p>
<p>After I have configured the kernel with "<span style="font-family:"Courier New",monospace">make menuconfig</span>" I make the kernel image with "<span style="font-family:"Courier New",monospace">make bzImage</span>". Next I try to make the modules with "<span style="font-family:"Courier New",monospace">make
modules</span>" and I am presented with this error: <br>

Hi Nick,<br>
<br>
yes, your should clone the repos; writing a new plugin is exactly what’s meant by “development.” If you want to hack the kernel or liblitmus: clone the git repos. If you just want to compile what we’ve released, it’s fine to use the tarballs.<br>
