In the second case, all parameters are reduced to the lowest end. I'd guess this is done to reduce bandwidth. Probably you have connected the device to/through a full-speed controller or hub (12 Mb/s, USB 1.x) instead of a high-speed one (480 Mb/s, USB 2.0). Are you using different ports? If not, does re-plugging help?
