I’ve got a BBB. I’m working on an Ubuntu laptop. BBB’s eMMC has unknown config, but SD card has Angstrom installed. I’m having issues connecting to the board via USB. It works 20% of the time. I tried with and without the udev rules (73-beaglebone.rules), I tried with with or without the ftdi_sio module loaded… I can’t get a consistent result. Possibly, my USB cable is not reliable… I’ll try to test with another one. I also tried with DC power supply in case my USB could not deliver enough power but it didn’t help.
The udev rules for BBB identify it from ID 0403:a6d0, but lsusb tells me that “1bcf:2885 Sunplus Innovation Technology Inc” is connected, and in case the connection is successful “1d6b:0104 Linux Foundation Multifunction Composite Gadget”. But not 0403:a6d0. So it seems the udev rules won’t be of any help… Can anyone explain the udev rules? I know the first one is to load the ftdi_sio module when the 0403:a6d0 device is connected, but I don’t understand the other rules.
Also, is there an error with the 0403:a6d0 ID? or is there something else going on here?
