I'm playing around with my new USB Host Shield and have encountered a problem. After these errors remove I can start with connecting the board. When I compiled the code board_qc, to check the board, it gave me several errors: board_qc:17: error: 'USB_DEVICE_DESCRIPTOR' does not name a typeīoard_qc:20: error: 'USB' does not name a typeīoard_qc.ino: In function 'void setup()':īoard_qc:27: error: 'E_Notify' was not declared in this scopeīoard_qc:31: error: 'Usb' was not declared in this scopeīoard_qc:33: error: 'rREVISION' was not declared in this scopeīoard_qc:56: error: 'rGPINPOL' was not declared in this scopeīoard_qc:103: error: 'rUSBIRQ' was not declared in this scopeīoard_qc:103: error: 'bmOSCOKIRQ' was not declared in this scopeīoard_qc:112: error: 'rUSBCTL' was not declared in this scopeīoard_qc:112: error: 'bmCHIPRES' was not declared in this scopeīoard_qc:113: error: 'rUSBIRQ' was not declared in this scopeīoard_qc:113: error: 'bmOSCOKIRQ' was not declared in this scopeīoard_qc:120: error: 'rUSBIRQ' was not declared in this scopeīoard_qc:120: error: 'bmOSCOKIRQ' was not declared in this scopeīoard_qc:144: error: 'Usb' was not declared in this scopeīoard_qc:150: error: 'USB_DETACHED_SUBSTATE_WAIT_FOR_DEVICE' was not declared in this scopeīoard_qc:151: error: 'E_Notify' was not declared in this scopeīoard_qc:153: error: 'USB_ATTACHED_SUBSTATE_RESET_DEVICE' was not declared in this scopeīoard_qc:156: error: 'USB_ATTACHED_SUBSTATE_WAIT_SOF' was not declared in this scopeīoard_qc:159: error: 'USB_ATTACHED_SUBSTATE_GET_DEVICE_DESCRIPTOR_SIZE' was not declared in this scopeīoard_qc:162: error: 'USB_STATE_ADDRESSING' was not declared in this scopeīoard_qc:165: error: 'USB_STATE_RUNNING' was not declared in this scopeīoard_qc:167: error: 'USB_DEVICE_DESCRIPTOR' was not declared in this scopeīoard_qc:167: error: 'buf' was not declared in this scopeīoard_qc:207: error: 'USB_STATE_ERROR' was not declared in this scopeīoard_qc.ino: In function 'void halt55()':īoard_qc:220: error: 'E_Notify' was not declared in this scopeīoard_qc:225: error: 'Usb' was not declared in this scopeīoard_qc.ino: In function 'void press_any_key()':īoard_qc:250: error: 'E_Notify' was not declared in this scopeĪnyone have any idea on how I can get rid of these issues?


To give it a kick start I downloaded the library USB_Host_Shield_20.
