Hello,

The token=0x01F38D08 occurs when adding or removing another USB device or when the USB device has been used for an extended period of time. The error may occur within 30 minutes or after multiple days of usage before the device stops communicating. Resetting the device or restarting the task results in the same error.

To solve the error, you can try the following tests:

• ​Disconnect the USB cable, then reconnect it
• Remove power from the USB device, then reconnect it
• Try replacing or using another USB cable

Is not error by software.

Regards
