Yes, that worked...

$ sudo usbreset /dev/bus/usb/001/005
Resetting USB device /dev/bus/usb/001/005
Reset successful

...and I liked it.

Why do you want to reset the hubs?  I thought you just wanted to reset 
the Huawei Internet stick.

There's no point.  If you specify the wrong device-filename argument, 
the program will reset the wrong device.  Or it will give you an error 
message.

Besides, you can try those experiments yourself and see what happens.

I noticed a while ago that the OpenWrt guys have made a few useful
changes to this utility, including the ability to name the device by
VID:PID. This makes it a lot easier to use:
http://git.openwrt.org/?p=openwrt.git;a=blob;f=package/utils/usbreset/src/usbreset.c

I've been planning to get that diff submitted to usbutils, but haven't
gotten around to it yet.  Yes, I move slowly ;)

Thanks, Alan.

I will look and test this (or adapt your) line as soon as I get in
front of my machine.

I have seen that the corresponding "usb-port" provides a usb3-hub and
a usb2-hub, so I think I have to reset both?
Are those hubs independent?
I will re-check my outputs which I had sent here.

Can you add an example-line to the "help-text" when invoking usbreset
with no (or wrong) device-filename argument?

Thanks in advance.

sudo ./usbreset /dev/bus/usb/001/005

001 and 005 are the Bus and Device numbers from the lsusb output.

Thanks for the feedback.

How do I identify the usb-hub where my Internet stick is plugged in?
IOW, what concrete "device-filename" do I have to pass to usbreset?

Nope, you need to point it at your hub.

But be aware that usbreset does not always work, at all, as not all
hardware hubs support this additional feature.

good luck!
