RB750Gr3 hEX vs RB751G - The maximum number of USB devices

Hello, I have a problem with the number of devices connected to USB. I connect:

  • active with an external HUB voltage
  • 5x 3G modem
  • 2x Pendrive

In the RB751G model, everything is correct.
In the RB750Gr3 model, hEX sees all devices, but mounts no more than 5.
Is this a software restriction? All new devices have USB device limits?

Interesting questions. Have you asked support? What did they reply?

I did not ask for support. I thought someone knew the solution.

Maybe there could be someone. But I personally do not remember that I ever saw such or similar information related to any of mikrotik devices. So I doubt you can get any relevant answer from the users here.

Sorry for offtopic but cant contact you privatelly.

@Angel83, what kind of LTE dongle are you using?

You can. Write here your email or Skype nick and I will contact you directly.
