Hi, everyone.
I am working on a project that uses uPD720201.
I am not solving one problem.
Please give me some advice.
The symptoms of the problem are as follows.
If USB3.0(SS) device is connected to one port and USB2.0(HS) device is connected to the other port,USB3.0(SS) is disconnected within a few minutes.
Other combinations do not cause problems.
- Port 1 : SS, Port 2 : SS -> OK
- Port 1 : HS, Port 2 : HS -> OK
- Port 1 : SS, Port 2 : FS -> OK
- Port 1 : SS, Port 2 : HS -> NG
For reference, the USB compliance test was passed.
Hello Steven!
How's it going? I tried to find some documentations that have some workaround regarding this but to no avail. I found a forum though, I thought you might try their ideas. Kindly refer to this link: https://forums.guru3d.com/threads/renesas-usb-3-0-driver-3-0-23-disconnect-bug.370257/
I hope that would be helpful. All the best!
