Can you add some steps for reproducing the issue? A code snippet?

I saw you also reported the same issue for the Android API communication implementation, and it's exactly the same error. Have you tried it on another device?

Please try the following:

• Try with another USB drive on the same phone
• Try with another app, another USB device on the same phone (i.e. a keyboard or mouse)
• Try the same USB drive on a different phone
