Yea I hear ya .. if it aint broke ... right?
I actually just found this post from ck on the matter .. I may give this a shot and see if it does anything. Easy to fall back if needed. I have a node running CKpool on a server in the same rack with these miners so I can easily test it out.
I suggest you take the top off the cointerror, pull out the usb cables from the beaglebone controller and plug them into any pc running linux. The device works fine from any controller running cgminer.
