it as well. The TTY patches contain some support needed for UGEN but there is more required. Let me take a look at it today to see how much more effort it would take to get the baseline UGEN compiling (in usb_dev.c).

By the way: I noted that the libbsd in your github repo is from December<br>
2016. There have been quite some changes since then including a mayor<br>
update to the FreeBSD head of 2016-08-23 and two smaller ones to more<br>
recent FreeBSD head versions. Also the WLAN support has been added since<br>
then. You might should consider an update if you still work with this<br>
version.<br>
