I have an A+ I wanted to try use on my local network, so I installed Raspbian to an SD card, have a USB to ethernet dongle, and added a blank "ssh" file to the SD card root to be able to log in to it from my Mac.

When testing the USB dongle on my Mac (WiFi off, USB dongle to ethernet cable to my router) it works fine, but when I power up the A+ the leds on the USB dongle don't even light up, nor can I find any new MAC addresses or IP addresses in my router connection monitor nor via nmap. My assumption is that the A+ and the dongle don't play nice, but could there be something I can try aside from just assuming device incompatibility? Could it be because of the first time setup something goes amiss?

The A+ lights both red and green lights shortly when starting, then has the red one on. It's getting power from the mini USB with power converter from an outlet. Also I don't really have any spare screen I could use to run the A+ by itself, so the ssh option is the way to go I'm afraid. The USB dongle is of brand Anker.

Any ideas what to try?

Edit: Here image of the USB ethernet dongle details as viewed when plugged into my Mac: enter image description here

    What "dongle" is it? Do you know if Raspbian supports it? Your RPi receives enough power? Without screen, you could still go for a serial console to follow your RPi booting. But I don't know if Mac has RS232, else you would need another "dongle", usb to RS232. BTW, what do you suppose to obtain with that "blank ssh file" ? – Gerard H. Pille Mar 9 '18 at 12:15

    My RPi's are heavier and need a healthy 2A, but yours can do with a lot less - but you need to power the dongle too. The dongle is USB 3.0, which made me worry, but they say its backwards compatible to USB 1.1. I doubt you'll get a Gigabit out of USB 1. Please put the dongle in the Mac and find out the Vendor and Product ID's. Also a link to one of the guides with the empty ssh file. – Gerard H. Pille Mar 9 '18 at 13:05

    This adapter works on Raspbian! raspberrypi.stackexchange.com/questions/32262/… If I read correctly, the module is dwc_otg. So something else is wrong. Can you read the MicroSD in your Mac? If so, you should try to read the logs, /var/log/dmesg, messages, ... – Gerard H. Pille Mar 9 '18 at 13:18

    I never used NOOBS (noblesse oblige) but normally there are at least two filesystems, no. 1 is the boot (VFAT), no. 2 is the root (ext4 ?). The logs would be on the second partition. This seems not to be the case for NOOBS though, all seems to be in a single FAT32 partition. – Gerard H. Pille Mar 9 '18 at 13:28

    On the screenshot here, raspberrypi.org/learning/software-guide/backup I see there is a /var folder. Didn't you find that one? – Gerard H. Pille Mar 9 '18 at 13:34
