Another audio question
I posted a question similar to this last week and thought I had the problem solved, but apparently not.
I have an external audio device I connect to my Windows 8.1 Inspiron 3847 desktop. This is a Technics keyboard (actually taken over by Panasonic). I connect it to my machine because I am a music notation copyist and use music software.
I have discovered that the USB device is only recognized by my system under certain conditions. First of all, the device was made prior to USB 3.0 so I plug it into a USB 2.0 port. But to my surprise, which USB 2.0 port I plug into make a difference. That is, if I plug directly into a port located on the front or back of my machine, it will not work. However, I have what I guess you call an extender four port USB hub. I plug it into one of the USB 2.0 ports of the computer and it gives me three additional USB 2.0 ports.
For reasons unexplained, when I plug my audio device into it, it gets recognized. If I plug it into any of the other on-board USB 2.0 ports on the computer, it does not. Go Figure? The only thing I can think of that is different is that the extender, has its own power supply. The error message when plugging into ports (other than on the extender) says "The last USB device malfunctioned and windows does not recognize it.
Anyone know what might be going on?

I only have two USB 3.0 ports and I have not tried the device on them. It is not clear to me how well things that were made for USB 2.0 actually work in a USB 2.0 port. But I have discovered two things. One, the external device with its own power does seem to make a difference, and two, I had a very long USB 2.0 cable I was using. It worked using the extended port, but not in the front USB 2.0 port. However, I found another cable (shorter) and it seems to work well in both.
This brings up another point in that it seems that all cables (that look like USB cables) are not created equal. It's a complex subject. I wish I had a better understanding of it all. Is there one type of USB cable you can and or should buy these days, that you can be relatively sure will work in a variety of circumstances?
Would there be some value in purchasing a USB 3.0 Hub with it's own power supply, Is there a point in time where you can just have too many hubs?
Thank you again
