Hello. I'm having an issue with libftdi and i have suspection about endpoints numbers.
But start from the beginning, error: 08-06 16:32:16.328: WARN/System.err(15547): ftdi_usb_open_dev() 08-06 16:32:16.328: WARN/System.err(15547): usb_detach_kernel_driver_np()libusb: 0.029116 debug [libusb_detach_kernel_driver] interface 0 08-06 16:32:16.328: WARN/System.err(15547): ftdi claim interface ... 08-06 16:32:16.328: WARN/System.err(15547): libusb-compat debug: usb_claim_interface: interface 0 08-06 16:32:16.328: WARN/System.err(15547): libusb: 0.030246 debug [libusb_claim_interface] interface 0 08-06 16:32:16.328: WARN/System.err(15547): claiming interface using fd = 4 08-06 16:32:16.328: WARN/System.err(15547): ftdi_usb_reset ... 08-06 16:32:16.328: WARN/System.err(15547): libusb-compat debug: usb_control_msg: RQT=40 RQ=0 V=0 I=0 len=0 timeout=300 08-06 16:32:16.328: WARN/System.err(15547): libusb: 0.031222 debug [libusb_get_next_timeout] next timeout in 0.300000s 08-06 16:32:16.328: WARN/System.err(15547): libusb: 0.031527 debug [libusb_handle_events_timeout_completed] doing our own event handling 08-06 16:32:16.328: WARN/System.err(15547): libusb: 0.032046 debug [handle_events] poll() 2 fds with timeout in 300ms 08-06 16:32:16.328: WARN/System.err(15547): libusb: 0.033023 debug [handle_events] poll() returned 1 08-06 16:32:16.338: WARN/System.err(15547): libusb: 0.033389 debug [reap_for_handle] urb type=2 status=-32 transferred=0 08-06 16:32:16.338: WARN/System.err(15547): libusb: 0.033755 debug [handle_control_completion] handling completion status -32 08-06 16:32:16.338: WARN/System.err(15547): libusb: 0.034091 debug [handle_control_completion] unsupported control request 08-06 16:32:16.338: WARN/System.err(15547): libusb: 0.034366 debug [usbi_handle_transfer_completion] transfer 0x2915e0 has callback 0x5ccb4 08-06 16:32:16.338: WARN/System.err(15547): libusb: 0.034732 debug [ctrl_transfer_cb] actual_length=0 trying to define the reason i found that the next endpoints numbers are used by default: from (usb.h): #define USB_ENDPOINT_IN 0x80 #define USB_ENDPOINT_OUT 0x00 from ftdi.h: #define FTDI_DEVICE_OUT_REQTYPE (USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_OUT) #define FTDI_DEVICE_IN_REQTYPE (USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_ENDPOINT_IN) actual endpoint numbers: 08-06 16:32:16.328: WARN/System.err(15547): avrdude: usbdev_open(): using read endpoint 0x81 08-06 16:32:16.328: WARN/System.err(15547): avrdude: usbdev_open(): using write endpoint 0x02 the problem is that i'm having different endpoints values and it's FTDI device definitely. since there is no way to set endpoints for my usb device i have the next question. 1. Why endpoints have such values by default? 2. How should i change them for libftdi correctly as i can't see any methods for this? Thanks in advance, Anton. -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details. To unsubscribe send a mail to [email protected]
