Part Number: TUSB2077A
Other Parts Discussed in Thread: TPS2071
Tool/software:
I am working with a device that supports high-speed and full-speed USB. I want to test this device working at full-speed USB, so I am looking for a USB hub board that works at 12Mbps (full-speed) in order to force my device to full-speed. The USB hub board must only work at full-speed, because otherwise the device will negotiate high-speed.
Which USB hub do you recommend that works only at full speed (12Mbps)?
The datasheet confirms that this board can also operate at High-Speed (480Mb/s), so that is not an option. As I mentioned, I have a device that is compatible with USB FULL-SPEED (12Mb/s) and USB HIGH-SPEED (480Mb/s). If I connect it to the TPS2071EVM board, as it is compatible with High-Speed (480Mb/s), my device will negotiate High-Speed and it will operate at High-Speed (480Mb/s). I want to force my device to operate at Full-Speed (12Mb/s) by connecting it to the PC. To do this, I need a USB hub that only works at FULL-SPEED (12 Mb/s).
