DOMException: The transfer was cancelled. on Pixels + Android 10 - and a possible fix

[andreban]

I've tested the sample here on a Pixel 2, 3 and 4, all of them with Android 10.

On those devices with Android 10, once connected, any call to device.transferIn or device.transferOut causes the transfer to fail with DOMException: The transfer was cancelled.

Removing the call to selectAlternateInterface here does seem to fix the issue.

I don't have great knowledge on the USB protocol, so would like to check before making a Pull Request to remove that call, as my guess is that it's probably there for a reason.

I have tested the code after removing that link on Android 9 + Nexus6P, and things seem to continue working as expected.
