hi,sir
Now we changed the length of usb3.0 cable,it's 2000mm. The previous parameters can not be used,how to set the EQ,DE,OS?
And There is a question to ask, we debuged a parameter, DE-H,EQ-H,OS-H,there is no problem when read U disk data , but when white U disk data, A transmission error always occurs, why?
Thank you very much and best regards.
Hello Walker,
Please try to increase the OS on both TUSB522, that should be enough.

Diego.
hi Diego,
what your mean is the system need twoTSUB522P or need make the two OS high?
As the current situation, the two OS is already high, but transmission error still occurs when Write data to U disk.
Whether there is a parameter to ensure that the transmission performance to maximize, that is, I use the short line or 3m line can work properly ?
Thank you very much!
Hi diego
thanks very much first, but the question not be solved completely.
when insert a USB3.0 U disk,the computer distinguish that is a USB2.0 device sometimes,it is very unstale on working。why? and the solution?
in addition, the length of the usb 3.0 cable is 1.5m, one end is usb type A, another end is PH connector。
thank you。
Hi Walker,
I understand the situation. In order to provide a precise solution, I need to have more information. It seems that the re-driver is working bot the configuration is not the best one for the channel, so the Host is not passing the polling step from the enumeration. Do you have a way to get an eye diagram from the port, or at least a log from a USB analyzer?
Regards,
Diego.
