>>10356 This info is probably not helpful, but maybe it is.
You're using USB versions (3.0, 2.0, 1.1 and 1.0) like speed values, but they are not. Partly independent of version, you get the following speed standards in USB (in order): SuperSpeed (5 Gb/s; Version 3.0) Hi-Speed (480 Mb/s; Version 3.0 and 2.0) FullSpeed (12 Mb/s; All Versions) LowSpeed (1.5 Mb/s; All Versions)
This means, even when using USB 3.0 devices, your devices can end up falling back to LowSpeed. A lot of Hi-Speed devices fall back to FullSpeed, depending on trivial things like cable length and quality, etc.. Just an USB 1.1, for example, device will never run on Hi-Speed or SuperSpeed. So upgrading from 2.0 to 3.0 does not guarantee SuperSpeed, but just makes it possible to go SuperSpeed in an ideal situation.
Also the transfer rates are "signaling transfer rates", meaning apart from payload, there will be some overhead from the USB system itself (device detection, speed negotiation, etc.). So even a SuperSpeed device may transfer much less payload, depending on what other info it transfers and what the other devices, sharing a host port/controller transfer.
Just sayan.
Good luck.
