TUSB7340: Unable to enumerate USB device

Gilbert Lien

Part Number: TUSB7340

Hi expert,

We found that only a few USB3.0 device can be recognized and all the USB2 device can't be enumerated.

Is there any setting we can check?

Thanks,

Gilbert

For type-C, you can not connect two USB2 ports on one C- connector, normally people shorts DP1/DP2, DM1/DM2 on connector.
