We have a credit card reader(verifone MX870) that is powered by USB port and communicate over serial port, which means checking device from the udevadm/lsusb output is not really mean that device connected and ready. Therefore, I will stay with current implamentation to send enquiry string to the device port and try to get the ACK form device. |
