The alarm company tell me that the USB connection is powered from their board and doesn’t ask for anything from RPi. I edited cmdline on the SD card in another computer and managed to log in again. I booted with only the keyboard gjc232a connected, then removed it and plugged in the alarm connection, so there shouldn’t be gcu232a load on the USB. Thanks for all the work on trying to fix this problem.

I think this the first technical underlined article I find about the issue. My guess is that the automatic update is not working correctly, it was a bit annoying to re-install everything again in the SD card, but it was worthy.

Maybe if the routine linix called again, the status register finally shows the correct status and the interrupt is handled. As far as your GPS is concerned, plug it in, and then have a look at dmesg. It might be worth a try to send him a PM.

OSX support as well, so, I’m curious about compatibility with linux. It has also changed Comm port number upon restarting the computer. You should just be able to double click on the file, and File Roller should open and it is pretty self evident from there.

Would it help to buy a powered hub? Or do I just have to wait until the USB driver gets fixed?
