Will USB 2.0 devices work on USB 1.1?
Shineway Electronics Co., Ltd.Yes, USB2.0 devices can work well at USB1.1 port, but the speed will be limited to the maximum speed of USB1.1, that is 12MBPS. The entire bus under the USB 1.1 root hub will slow to 12Mbps. The operating system will probably notify the user about the sub-optimal configuration and recommend for a better course of action.
Related QuestionsDo USB 1.1 cables work with USB 2.0 devices?
Computer TipsIdeally, yes. USB 2.0 architecture uses the same cables and connectors as USB 1.1 compliant products. Unfortunately, only 3 out of 11 cables on the market are certified as USB 1.1 compliant. You may run into the cables that cause problems connecting high-speed peripherals. To avoid negative user experience, most vendors include USB 2.0 compliant cables with their USB 2 PCI cards and peripherals.

Will USB 1.1 devices run any faster on a USB 2.0 bus?
Computer TipsNo. However, the new USB 2.0 archiclecture allows more high-speed USB 1.1 devices, such as web cams, audio devices, to share the bandwidth. Developers need to follow USB 2.0 spec in order to design higher speed peripherals that can take advantage of the extra bandwidth. USB 1.1 devices still operate at 12Mbps at full-speed and 1.5Mbps at low-speed on a USB 2.0 bus. Even though USB 1.1 devices won't run any faster, they can work alongside of USB 2.0 devices on the same bus.
Related QuestionsWhat happen if a USB 2.0 devices are plugged into a USB 1.1 systems?
Computer TipsThe entire bus under the USB 1.1 root hub will slow to 12Mbps. The operating system will probably notify the user about the sub-optimal configuration and recommend for a better course of action. If several USB 1.1 hubs are connected to a USB 2.0 bus, then each of the USB 1.1 hubs will get a full 12Mbps bandwidth.
