cool, great to hear (perhaps not for you ) , but means we don't have a general issue
if your having issues with a few devices, yeahs its possibly time for a change...
one thing you could try, is using a different usb hub, as they are 'not all equal',
I'd recommend a USB 2.0 powered MTT hub, I use a this one Pluggable MTT Hub, the important thing is it support MTT, which unfortunately is not often stated. (this one uses the Terminus FE1.1SB chipset which has MTT)
It may or may not solve the problem, as we don't know what the issue with the hub is... but its a useful hub to have around anyway when dealing with multiple USB 1.x devices (I got it due to my Virus, and have been very happy with it)
(Just to be clear to others, we have no reported issues with using hubs etc, this issue sounds it could be a 'one-off', but we will monitor)
Anyway, really glad to hear, that you are up and running with Axoloti, and can start exploring its depths ... enjoy
