Why doesn't usb work on Mikrotik RB2011UiAS-2HnD-IN?

Question

Mikrotik

I connect a USB device, whether it's an lte modem or a flash drive, through a regular usb-microusb adapter, the microtic refuses to see the device, only serial0 continues to hang in the ports. The adapter is checked on the tablet - that flash drive was read normally.
Either I'm a fool, or the skis don't go, but this is already on two routers (the model is the same). Maybe something needs to be tweaked somewhere?

Answer 1

I can advise you to connect using an injector or through an active usb hub. In many cases, the problem is malnutrition.

Answer 2

reboot with connected device =)

Answer 3

do this:
Remove the power from the board, unplug the modem, then plug the modem back to the
board and only then power on the board.
then check if the modem is recognized or not.
I have earned. and it gives enough power for any whistle.
you can also look in /system resource usb print if it's like:
[admin @papa -admin] > /system resource usb print
# DEVICE VENDOR NAME SPEED
0 1:1 Linux 3.3.5 ehci_hcd RB400 EHCI 480 Mbps
1 1:11 HUAWEI Technology HUAWEI Mobile 480 Mbps
means everything is fine.

Answer 4

Okay, thanks, I saw the flash drive in resources - usb.
Let's go further.
Yota 4G Lte WLTUBA-107 refuses to see. In the Mikrotik wiki, this model has compatibility with 6.0, okay, rolled back to 6.0, does not see it. The LED on the modem is off.
What could be the trouble?

Answer 5

Hmm. Did lte not appear in the interfaces when rebooting?

Answer 6

Thank you, maybe it really is about food. But they already installed another router, no matter how much I didn’t want to. (and it’s over about the vpn client in this router they didn’t hear, but it’s free)
