Hey Freezen, I am having a huge headache with USB, as well. This is how I have solved the problem, somewhat indefinitely, but I would love your feedback and perspective on it.
So, I have a very nice USB hub, Multi-TT, yadda yadda: https://www.google.com/shopping/product/16657881332461573039?q=multitt%20hub&client=ubuntu&hs=6zE&channel=fs&biw=1301&bih=678&ei=NqCKUprbLaWViALGyICgDg&ved=0CKEEEKYrMAE&prds=scoring:p (you can find it cheaper) Apperently Hot-Plug works IF the hub you have is booted with a device installed in it. For example, I can hot plug in a wireless adapter so long as I have a thumbdrive installed in the hub when my BBB boots. I Imagine your xbee's will be installed in the hub when you boot, but if they drop out and come back in, you may get a USB Babble Error if there is nothing else in the hub. https://github.com/beagleboard/kernel/issues/64#issuecomment-28486198 Maybe getting a decent hub and leaving a thumbdrive in the hub will make your system more stable. I know, it's a lame solution, but it is what it is. Another possibility is just getting some xbee breakout boards and connectiong the XBee directly to your BBB's tty's. A protocape and a pair of XBee breakouts would get you around the USB subsystem completely. This might be preferred, anyway. http://www.droids.it/cmsvb4/content.php?143-990-001-XBee-Simple-Board or https://www.sparkfun.com/products/8276 https://www.sparkfun.com/products/8272 with http://www.adafruit.com/products/572 On Fri, Nov 15, 2013 at 9:45 PM, <kfree...@gmail.com> wrote: > Hi, > > Thanks for the suggestion.
