Not quite, there is no module requirement if you are mining with cgminer 3.2.1+ as it uses direct usb communication and will unload that module you just recommended.
Oh, thanks. Is there a reason for using direct USB communication? More efficient?
Yes, to bypass one layer between cgminer and the device, and give us more control over it. It has allowed us to shave a lot of CPU off by doing so. It is unfortunately a lot more work, and keeps revealing to us interesting hardware limitations that the drivers paper over, but that is often the case that the better solution takes more effort.
