[−]

A USB stack error.

Variants

WouldBlock
[−]

An operation would block because the device is currently busy or there is no data available.

ParseError
[−]

Parsing failed due to invalid input.

BufferOverflow
[−]

A buffer too short for the data to read was passed, or provided data cannot fit within length constraints.

EndpointOverflow
[−]

Classes attempted to allocate more endpoints than the peripheral supports.

EndpointMemoryOverflow
[−]

Classes attempted to allocate more packet buffer memory than the peripheral supports. This can be caused by either a single class trying to allocate a packet buffer larger than the peripheral supports per endpoint, or multiple allocated endpoints together using more memory than the peripheral has available for the buffers.

InvalidEndpoint
[−]

The endpoint address is invalid or already used.

Unsupported
[−]

Operation is not supported by device or configuration.

InvalidState
[−]

Operation is not valid in the current state of the object.
