I'm trying this out with a Huawei E398 v:12d1 p:1505 on Ubuntu Mate.

I'm not sure what the problem is but trying to auto switch from udev works now and again but generally not. Then after bootup when I run the switch command it seems to be ignored the first time. Well when I say it's being ignored it does output what looks good but there's no change on "lsusb".

When you re-run the same command you get the same output to the terminal and this time it works

Ideally I'd like to get this to work from udev as it's going to be used by end users who aren't going to like issuing "sudo" commands.

Raspberry pi with its crappy dwc_otg usb root hub driver, tell the maintainers of your distro to use the dwc2 driver.
Nothing we can do here, they are the only ones who can fix the problem.

Cheers LOM,

thanks a million for that information. I'm running Ubuntu Mate so not sure what to do next. Might be possible to upgrade.

So dwc2 is part of the kernel, but dwc3 is in there as well. Should I be rolling a kernel with dwc2 or jumping to dwc3?
