"lsmod" verified that "option" was loaded. "dmesg" gave this after a reconnection: usb 5-7: USB disconnect, address 25 option: option_instat_callback: error -108 option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0 option 5-7:1.0: device disconnected option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1 option 5-7:1.1: device disconnected option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2 option 5-7:1.3: device disconnected usb 5-7: new high speed USB device using ehci_hcd and address 26 usb 5-7: New USB device found, idVendor=19d2, idProduct=2000 usb 5-7: New USB device strings: Mfr=2, Product=1, SerialNumber=0 usb 5-7: Product: ZTE CDMA Technologies MSM usb 5-7: Manufacturer: ZTE, Incorporated usb 5-7: configuration #1 chosen from 1 choice scsi32 : SCSI emulation for USB Mass Storage devices usb-storage: device found at 26 usb-storage: waiting for device to settle before scanning usb 5-7: usbfs: process 28251 (usb_modeswitch) did not claim interface 0 before use usb 5-7: USB disconnect, address 26 But still the same result. The modem configures well, but does not connect.
