Hi All,
I wonder if anyone ever succeeded in getting the USB 2.0 port of this board work properly.
I'd like to (try to) use it as a *very* low cost ADS-B receiver using an external RTL-SDR dongle, but despite the fact that the port is claimed to be a 2.0 (and recognized by the OS as a 2.0 Hub) when I attach the dongle (which is a high speed 2.0) no driver are loaded and is instead recognized as a full speed device, therefore the RTL-SDR library stops working with transfer errors, since it needs the 480M transfer speed of the 2.0 port and is unable to work with the 12M speed of the "full" standard.
Here is my dmesg | grep usb

I wonder if it can be a power-related problem, but I tested all the three power adapters I own, two 2.1A and one 2.4A, two of which with mobile USB cables and the last with fixed cable which work without a problem with my OPI Lite and my OPI Zero (each one having mounted to their USB ports an RTL-SDR dongle, plus a CPU fan, SSD1306 OLED screen and external RTC module attached to their GPIO header).
I doubt that the same power unit that is able to drive a 4-core board with all that stuff attached to the USB and GPIO header (and in the case of the Zero powered through the same micro-usb port) is unable to deliver enough power to this single core board and just one device attached. Or am I wrong?
I tried with any possible combination of power adapters and cables I have and even tried to (succesfully) power up the board through the GPIO header's pins, but nothing changes.
I also tried to switch the RTL-SDR dongles, I have three, but all of them are recognized as 1.1 devices while they work as they should with the OPI Lite and Zero.
I tried also to attach different USB 2.0 pens to the board but even these are recognized as 1.1. devices.
I tried to attach an external 4-ports 2.0 Hub, I have two, one is powered, the second is not. The powered one is simply not recognized, the other one is recognized as a 2.0 Hub but if I then attach the dongle to it, the dongle is not recognized anymore (not even as a 1.1. device).
I then tried to use a Y USB cable to provide this latter hub some external power (by attaching the power cable to a second power adapter) but nothing changes (the hub is recognized, but no other devices attached to it are).
At this point I wondered if the problem is somwehere with the drivers, I tried both the OrangePI provided images (Debian and Ubuntu) and the Armbian images that the user guidol (thank you, you did a great job!) managed to compile a couple of years ago, but nothing changes.
Lately, even if I am a noob with Linux in general, I was considering trying to venture compiling an Armbian image myself just to see if anything improves, but I seem to understand that the board is no more supported and so it cannot be used anymore to compile an updated image, is that right?
Should I try to buy another power adapter? maybe a 3A unit? Before doing this I'd need some feedbak anyway, as it would cost more than the board and the SDR-RTL dongle together!
Any other advice someone?
Is anyone using succesfully this board with a high-speed (2.0) device??
It's a pity because despite the flaky WiFi connection, which should not be a great issue for the use I'd need, the image compiled by guidol works flawlessy.
Thanks anyone for any help.... BTW: THANKS YOU ALL GUYS for the great work you are doing with Armbian! I'm new to Linux but I really hope one day, when I will knew a bit more, to be able of giving something back to the community.
