Hi,
I am using TUSB2036 to split USB connectivity into 3 USBs. I took as a refferance datasheet and "USB 2.0 EMC Stick with integrated ESD Protection and EMI Filter" [1] from Wurth Electronic to add protection filter to the input.
My problem is that sometimes it cannot be detected by the computer (Windows 11). However, once connected to the computer, it can continue without any problem even after multiple power off-on attempts.
I notice that, when it is not detected, it can be detected after reset pin has been pull down and released.
Why does it not start properly at the power on?
We have produced over 500 of these cards and this connection error worries me. I welcome all your help.
Link and HUB schematic is at below.
Kind regards
