BananaPi Router R1 small pin header?

Question

Hi,

I hope this ("banana pi") fits here ("raspberry pi") ...

I have a Banana Pi R1 which is my central home-automation hub and, thus runs 24x7. I have now attached a DVBSky receiver using the only USB port available but I would need some more USB stuff. I tried a USB hub, but as I also have a webcam attached, this seems to switch everything to USB1.1 and the DVBSky doesn't like that.

Now I was thinking if there may be another USB connector available, eg on the small 8-pin header next to the IR receiver.

I have not been able to find a description referring to that connector (or to the two pins next to that).

Thanks,

Josef

Ah ... found it in the BPi schematics: The 2x4 header has UART7_TX, UART7_RX, "PH3", "PH5" and some power lines. The 2-pin header next to that has UART0_TX and UART0_RX. Josef

Would second USB hub solve the problem? HUB -> HUB -> webcam? Or some kind of "smarter" hub that can run ports on 1.1 and 2?

I don't think it has another USB as it is used internally for other devices (wifi, net).

That sounds like an unsuitable hub. Many USB 2 ones aren't very good. I'd suggest a USB 3.0 hub - you won't be connecting the USB 3 wires, but the quality of chips inside is much better.

So no USB there. However there is a USB OTG port, so with an adapter:

(I searched for 'micro usb otg')

you should be able to connect another USB device.

Well, aamof it IS a USB3.0 hub (a German brand "LC-Power LC-HUB-ALU-2B-4") but it says in the manual that it switches to 2.0 if you plug in a 2.0 device.

That's a good hint. I'l try that ... once I get a stable OS running.

Thanks!
