Application Fails to access USB Type-C Drive

[Anu P]

Hello,

I am developing an application to access USB mass storage drive connected to my phone.

When I create application, application is able to access USB drive in all devices having micro USB port.

When application is running in Nexus 5X or Nexus 6P, application is unable to access the USB drive. When I see the log, I can see the following exception.

It looks like SCSI command is issued, but no response is received and hence IO Exception is raised.

Any clue on the issue?

Any help to resolve the issue is highly appreciated.

Thanks,
