Hello
- cyusb_bulk_transfer returning -7 indicates that there is a timeout in the data transfer. Please refer to the following link.
- To avoid this, make sure that data is transferred within the specified timeout interval or the timeout value can be increased. Even if the error occurs, data transfer following that transfer could clear the issue.
Best regards,
Srinath S
