When running Mavericks connecting via USB to my BBB Rev A6A was amazingly simple.
After updating to Yosemite I’ve not been able to successfully install/re-install the USB/Network or Serial drivers or to connect to the board at http://192.168.7.2/
I’ve downloaded, reinstalled latest HornDIS rev 7 drivers and FTDI 2.2.18 serial drivers and restarted my laptop numerous times but still cannot connect to my BBB as before with Mavericks.
I too would love an answer to this issue. From what I’ve read the developer doesn’t even know what the issue is; however it has something to do with the HornDIS rev 7 drivers or FTDI 2.2.18 packages.
One factor that plays a huge part in connecting to the BBB is the quality of the USB lead.
We had issues when using longer leads, which seemed to be physically thinner than those supplied with the boards. Once the shorter fatter leads were used connections tended to be more consistent.
confirm that BBB USB comms working perfectly on Yosemite, Win7 and Debian 7.8 Wheezy here (triple boot mb air 4,2). Installed directly off the BBB’s web page.
