    hello guys, I notice two errors when my external hdd is plugged. 1. I got that crash when I try to launch snes9x gx with channel forwarder, when I click start it crash. No problem if the hdd is unplugged. If I run snes9x gx trought homebrew channel, no crash while hdd is plugged.

    2. I also notice wiiApple crash when I launch it while hdd is plugged.

    Everything is fine but that. I can run games on hdd with usb loader without crash etc.

    Any ideas ? :)

    ISI is unauthorised function execution.
    find a different forwarder ?

    You posted your issue in the Wii section, but are talking about vWii.
    maybe you installed the WII Version of the forwarder in your vWii so the launch method is not appropriate.

    There is a thread (in the WiiU section of the forum) with many forwarders converted for vWii.
    the thread is called "forwarders are back".

    That's is what I tought but I make sure I have installed the vwii version and the emulator is not on hdd but on sd card, I it strange if it work when I unplug it. Plus, wiiApple is not as channel forwarder and still crash if the hdd is plugged.

    Do you have another USB device you can connect to test?
    maybe there's a software issue, like mounting the FAT or ntfs partition, or you have a GPT table and only MBR is working with that channel, etc.

    Bad USB cables? Not using both ports?

    My external hdd is 1tb seagate with a power cable, I use only 1 usb port. I will try to use the other usb port to see and I will also check if it is usb 3.0, I read somewhere that may cause somes problems :)

    Well, no wonder it doesn't work; the Wii U has to use two USB ports for a self-powered HDD because one port does not provide enough power unlike the Wii did. USB 3 is compatible with USB 2, I used a USB 3 cable just fine with my USB HDD.

    Ok, that is why my hdd is cable powered, because I use the other usb for a wireless keyboard.

    With the Wii U, both USB ports have to be used, otherwise, insufficient power to the drive will cause issues. You'll need a USB y-cable.

    USB 3.0 is compatible with 2.0 if the protocol stack and device supports it.

    I personally never had any issues, he can still try a y-cable.

    This is true, but I think the protocol fallback is up to the device so some inexpensively-designed ones might rely on a driver to handle it.

    Are you using both USB ports? If not, having insufficient power can cause issues.

    I think the problem was not the fact he is 3.0 usb but he has some kind of defect because he just passed out, no more power, the motor doesnt run anymore and I see nothing on windows. That could explain the crash on wii sometime :)
