TUSB8041: Questions for TUSB8041 Different OS Application Issues

Jacky Wang(QD)

Part Number: TUSB8041

Hi Experts,

Our customer has a use case for TUSB8041 is to switch between Android OS and Windows OS sometime, block diagram showing as below. Now they found one issue is:

1. Switching in Android OS USB2.0, connected U-disk to downstream USB ports can be detected.

2. Then switching to Windows OS using USB3.0.

3. Then switching to Android OS USB2.0 again, inset the U-disk to downstream USB ports, but it can not be detected, unless you reset TUSB8041 by GRSTZ pin.

Do you know what's the problem in here?

Thanks a lot!

Hi,

We have not seen this issue before. Is TUSB8041 detected in step three and not the U-disk or both devices not detected?
