BeagleBone Black: Unable to load g_serial module

[steev]

Does it work for you if you use "modprobe g_serial stall=0 removable=1 nofua=1" I haven't tried the g_serial driver myself as I normally just use an actual adapter connected to the pins, but I'm looking into this.

root@kali:# modprobe g_serial stall=0 removable=1 nofua=1
modprobe: ERROR: could not insert 'g_serial': Invalid argument

Does this still fail to work for you with the 2.1 release?

[strasharo]

The module is no longer present in 2.1:

root@kali:# modprobe g_serial
modprobe: FATAL: Module g_serial not found in directory /lib/modules/4.4.0-armv7-devel-r28

There is a 2.1.1 image that hasn't been posted yet, unfortunately, and the g_serial module does exist there (just checked). Please try again once it's posted.

[strasharo]

Sure, will give it a go once the image is available and I'll report here the status.
Thank you.
