Finally all the hubs work fine. The solution is: copy /boot/dtb-4.10.11-sun8i/overlay/sun8i-h3-usbhost0.dtbo to /boot/dtb-4.10.11-sun8i/overlay/sun8i-h3-usbhost1.dtbo change ehci0 to ehci1 and ohci0 to ohci1 in /boot/dtb-4.10.11-sun8i/overlay/sun8i-h3-usbhost1.dtbo insert to /boot/armbianEnv.txt line: overlays=usbhost0 usbhost1 usbhost2 usbhost3 reboot

Thank You! The line in /boot/armbianEnv.txt: overlays=usbhost0 usbhost2 usbhost3 enables other usb hubs, but not all (old kernel lsusb shows 8 hubs, but new one only 6), with/without usbhost3 param. Still looking how to switch on the port I need.

@Igor I've just checked both last stable and experimental branches, with the same result. lsusb did't show any devices but two hubs. oops, looks like stable branch works fine (took some time to start usb device)

Any chance to try to touch device with fingers?

It works with OS from friendlyarm (nanopi-neo-ubuntu-core-qte-sd4g-20170331.img.zip), so I guess, it is armbian related problem..

Have tried to connect another USB device (mouse) with same results..

Nano Pi Neo, Armbian (Armbian_5.27.170422_Nanopineo_Ubuntu_xenial_dev_4.10.11) External USB device works fine when connected via USB-A jack, but doesn't work when connected to 2.54 pin header (2,3). Is there some additional steps to activate internal (usb1, usb2) ports, or it's hardware problem?

@martinayotte Thanks for suggestions. Unfortunately the only one usb port is used by external usb-sensor, and there is no internet access in the field. Probably, I can use secondary usb-port via 2.54 pins, but it requires a lot of hardware modification (include reroute on-the-top board and redesign 3D case). I'v tried to modify build scripts, and made some hardcode hacks to make an additional partition (first, FAT). At this point, I have to configure u-boot somehow, to boot from second partition, and still looking for variables/script to be modified for it.

@martinayotte Thank You. I'v tried to make new FAT partition at the end of SD, but it seems Windows can not see this one. Disk manager says, that second partition is RAW (not formatted), and when I try to format it, Windows destroys first partition for some reason. I guess there is a special partition table, which Windows does not understand.

A board (nanopi neo) collects some information and stores it to SD card. Users than change the SD card and open it on PC (windows). Due windows limitation, there is only one (first) partition (fat/ntfs) can be visible. Current mainline image for nanopi neo contains only one ext4 partition, so I tried to gparted it (moved first partition and made new FAT16 one), but for some reason, the image did not boot. So I'm looking for info, how to make two partitions properly.
