It's a long story so please bare with me.
Bought the BeagleBone Black somewhere in October. The USB host port worked fine. No issues with cold plugging and no issues with hot plugging. I screwed something else up and had to reinstall the OS. Got the 'latest image' from http://beagleboard.org/latest-images, which dated back to june 20th. It seemed reasonable that this was in fact the latest image. Succesfully flashed the eMMC using the angstrom image from june the 20th. Issues arose with the USB host port. No issues with cold plugging. However, hot plugging no longer worked. No error messages were sent to the journalctl when hot plugging, it just didn't seem to detect it at all. When a coldplugged USB device was removed journalctl reported messages like: usb 1-1: device descriptor read/64, error -19 hub 1-0:1.0: unable to enumerate USB device o... 1 hub 1-0:1.0: port 1 enable change, status 00000101 After that once again no activity when hotplugging the USB device. I thought that this was because I was now using a newer image than the image that was installed on the eMMC when I received my BeagleBone Black. I found a patch on github that basically FIXED an issue with hot plugging devices in the BeagleBone Black. It indicated that I probably was now using an older image than the one my BeagleBone Black was shipped with. After a chat with jkridner it became known that the latter was true. The 'latest images' were in fact not, the latest images. He updated the image to the actual latest image (of October the 4th). I then flashed the eMMC with the image of October the 4th, only to find out that I was still having issues with hot plugging USB devices. It's not a power issue, I'm using an external power source and error -71 would've indicated a power issue but I'm getting an error -19. I haven't been able to find any information about error -19 online. I'm completly confused and lost right now and I hope someone here can at least point me in the right direction. Thanks in advance for the time you've invested in helping me! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
