I'm using a Logitech USB Desktop Microphone.
It works perfectly when connected directly to the PC. However, if I connect it via a USB hub, it still is recognised, but I get all kinds of crackles and distortions.
How can that be? Shouldn't this be completely digital? How can the USB connection affect the recorded sound? Any troubleshooting tips to find the cause and/or fix this?
UPDATE: I bought a Belkin active USB hub. It seemed to be not-very-low-quality, but unfortunately it shows the same issues. :( Recommendations of specific USB hub models are welcome, I don't really know how to choose one that doesn't have this problem.
UPDATE 2: Is this maybe a problem with my specific microphone? Do you think another USB microphone would work on the same USB hub?
