R PI zero not detecting Alpha AWUS036NEH #216

Hi All

First, thanks for making this Awesome project so easily accessible.

I am experimenting EZWB with an unsupported wifi card, primarily because it is smaller and has the potential to fit on a 5 inch quad.

I have a AWUS036NEH USB WiFi Adaptor, 2.4GHz, which has a ralink 3070 chip in it. It supports monitor and injection and therefore, I can confirm this works as a transmitter and receiver on the regular raspberry pi B+.

However, I am struggling to get it to be detected as a USB device on the r pi zero. It won't appear using the command lsusb. I have tried additional power supplies and repeatedly swapped it in and out for my regular Alfa Network AWUS036NHA which works as normal.

I have even used the same EZWB sd card between r pi B+ which works and r pi zero which fails to detect it.

Do you know why this might not be detecting? I tried upgrading the r pi firmware but no luck.

I guess it is something related to the USB OTG r pi implementation or some incompatibility between the ...NEH and r pi zero.

I have ordered a 4uzero usb hub for the zero, which uses a different USB chip to link the two between, Ill, let you know how this pans out.

Thanks regards, great work, James

I confirm that the AWUS036NEH does work on the r pi zero. It works, however i needed to use it with a usb OTG cable. not just the two data + and data - wires like the alpha AWUS036NHA used only. I'll have more details soon.

It turns out that if one grounds pp40 and pp35 on the r pi zero it works. This is not necessary for the Alpha ...NHA
