I have a Philips PSC805 USB audio device which has been working fine for several years on a USB 1.0 hub. I bought a new 2.0 hub and can't get it working.
Here's a trace form plugging it in and they trying to play something. All that is plugged into the USB 2.0 hub is a USB 1.0 keyboard and the USB 1.0 audio device, it can't possibly be out of bandwidth.
