Hello Team,
We are trying to configure HX3C USB Hub. Earlier device is detecting but it is showing as Unknown device. But at present it is not detecting at all. Attached schematics, hardware setup for your reference.
In schematics we used pogo pins (J92, J109, J110, J111, J112, J113, J114) to interconnect the mother card and daughter card of USB Type C receptacle.
With 3.0 USB Type c there is no positive result. Trying from past few months. Still can't able to achieve. Kindly suggest possible solution to overcome this problem.
If we go with 2.0 USB micro B. Can we achieve our configuration. If yes, kindly suggest how to configure HX3C using usb 2.0.
Regards
Srinivas

Hi Srinivas,
USB Enumeration at High speed won't be reliable with jumper cable connection on D+/D-. So, this is HW issue.
You shall refer AN91378.
For configuring HX3C, you shall use HX3 Blaster Plus tool.

Hi Srinivas,
From the attached image, I can see that the mother card and daughter card interconnect has been achieved using jumper wires. This is against USB specifications since it will not guarantee the required channel characteristics for USB signals.
Is it customer's requirement to have a seperate mother card and daughter card? The recommended way is to place the Type-C connector on the mother card itself and route the USB signal lines according to USB routing guidelines.
