Can't always boot from usb-stick using usb-hub #15

Description

@PrivacyDragon

When I use an usb stick to boot linux, all goes well.
If I attach the calculator to an powered usb-hub with the usb stick in the hub, the stick isn't found.
Though sometimes it works, other times it doesn't.
Am I doing something wrong or is this a bug?

I use the mini A <-> mini B cable to connect the calculator to the hub. The A-side goes in the calculator.
Calculator model: TI-Nspire CAS
Production code thing : P-0510B
OS: 3.6

    Hmmm.
    I think the problem is with the usb-hub. I found an article online about something called 'backfeeding', which much cheap usb-hubs do.
    Since I have a cheap one, I guess that backfeeding might be the problem?

    Closing this for now, since it seems to be not a bug at all I guess...

    Ok. My guess was wrong. 'backfeeding' is not the problem, my usb-hub has a protection against that....
    So then I don't know what the problem is.
    Reopening this issue.
