Hi, I am using the usb serial pl2303. I can communicate using pl2303 soon after the boot-up. But, If I disconnect and reconnect the PL2303, then I am failing to restart communication? I think this should not happen, getting the logs as usb 3-1: USB disconnect, address 2 usb 3-1: pl2303_read_int_callback - usb_submit_urb failed with result -19 pl2303 3-1:1.0: device disconnected usb 3-1: new full speed USB device using brcm-ohci-0 and address 3 usb 3-1: configuration #1 chosen from 1 choice pl2303 3-1:1.0: pl2303 converter detected usb 3-1: pl2303 converter now attached to ttyUSB1 there is an error : usb 3-1: pl2303_read_int_callback - usb_submit_urb failed with result -19 Any idea on this behavior Regards, Prabhu -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
