Hello, my setup is:
Host PC ------>(USB A to USB B cable 0.5 m)--------->TUSB1002EVMRe-driver------------> USB 3.0 stick memory
Host PC ------>(USB A to USB B cable 0.5 m)--------->TUSB1002EVMRe-driver------------> (USB A to USB A cable 1.5 m)-------------------> USB 3.0 stick memory
I've tried USB 3.0 and 3.1 ports,
I've also tried different jumpers configuration for the EQ and Config
But the behavior is always the same: I see the device behind the Re-driver in USB 2.0 mode.
I cant get transfer rates over 40 MB/s
Note that with USB 3.0 windows advises that the device can be connected to SS port.( it is already connected to SS port)
I've tried also in linux and I could check that the connection detected was 2.10 same as windows.
So I'm out of ideas to figure out how to see a device behind this re-driver working successfully at 3.0 Mode.
Thanks in advance for the answers.
Hey tikitaka,
Could you send along your jumper config? Could be helpful to us in diagnosing the issue.
Best Regards,
Nick
Tikitaka,
Can you get eye measurements, so we can estimate the correct EQ settings for your implementation?

Hello Again,
We could measure the signals TX and RX with a differential prove on the USB3.0.
We can just see some communication when device is plugged in, then we have no signaling anymore.
It moves to USB 2.0.
Then we try most of the EQ configurations and CFG options without success. ( reseting the device each time)
We dont know why is so difficult to see USB 3.0 interface working through this Re-driver.

Hello Tikitaka,
Perhaps it is the same incompatibility issue that this post describes. The workaround is to include AC capacitors on the RX differential pair, as described in the post.
