I purchased a Beaglebone Black (rev. A6) at the end of last year and was highly unsuccessful in getting the board up and running on my desktop PC. Unfortunately, due to work and grad. school commitments I haven't made time to pursue this board any further until now.
Now onto the actual problem... I am unable to connect to the default web server over the USB connection on my desktop PC. Up until recently I was able to get the BBB mounted to my PC, however, after some tweaking last night I am now unable to do that either. I only tried very briefly to connect via the RJ45 connector on the board and was unsuccessful in that as well. I will say that I am able to connect to the BBB over USB on my laptop very quickly and easily so I really don't expect this to be a hardware issue.
My desktop PC is a Windows 7 64-bit machine that hasn't seen a fresh install in probably 2-3 years. In that time I've run a couple of different development boards (Arduino and a couple of simple PIC setups) plus a ton of other random peripherals. I also currently connect to the internet through a VPN and installed a TAP driver to do so. I have a VM setup through VirtualBox which has an entry in the network adapters section of the device manager labeled "VirtualBox Host-Only Ethernet Adapter". I guess the takeaway here is that I've been using this install for a few years now and have install all kinds of different device drivers for various peripherals that may be conflicting with my BBB. My laptop on the other hand is a new (<1 year old) Dell which is also running Windows 7 64-bit but has had far less connected to it.
As of early last night I was able to connect the BBB via USB to my desktop PC and see the BBB mounted to my PC. There were entries in the device manager for the Beaglebone (under Portable Devices), the Gadget Serial (under Ports COM & LPT), and the Linux RNDIS Ethernet gadget (under Network Adapters and shows up as Linux USB Ethernet/RNDIS Gadget #2 for some reason). The RNDIS entry showed device error 10 saying that the device was not able to start. I have installed the drivers through the BONE_D64 executable as well as by trying to manually update the driver and point it to the RNDIS driver located at F:\Drivers\Windows\src\files\RNDIS. Later last night I tried uninstalling all of the BBB entries I could find within the device manager (the three I listed above) and used bcdedit to allow the installation of digitally unsigned drivers thinking that perhaps Windows was blocking the install somehow. I restarted my PC, installed the drivers, re-enabled driver integrity checks with bcdedit and restarted my PC once again. This was unsuccessful and I was still unable to get the Linux USB Ethernet/RNDIS Gadget to start properly.
I also tried uninstalling all of the drivers, restarting, installing Code Composer Studio 5.5.0, and restarting again in the hopes that the software would be packaged with a digitally signed set of drivers that would run properly on my machine. Again, this was met with no success and I was still unable to connect to the BBB's internal web server.
Lastly, I tried downloading and flashing the BBB with the latest Angstrom image to see if maybe there was some weird interaction between the particular version of Linux on my BBB and my PC (despite it seeming unlikely due to the error with the RNDIS gadget). This last step was again unsuccessful, but I am still able to connect over USB to the BBB's webserver on my laptop.
I'd really like to solve this issue asap but I am out of ideas. I will probably be reinstalling Windows in about a month once my new SSD is no longer on back order. I am hoping that there is a solution someone else knows of that will get me up and running faster than that though. Working on my laptop is an option but my desktop has far more RAM which makes it much more appealing when I am running a VM to develop code for the BBB. Hopefully I've provided enough information for someone to give me an idea of what else I could try. Thanks in advance for your help guys!
