Hi Hans, dmesg doesn't say anything when the failure occurs. # sysctl hw.usb.no_cs_fail sysctl: unknown oid 'hw.usb.no_cs_fail' I turned on debugging in the modem driver # sysctl hw.usb.u3g.debug=1 hw.usb.u3g.debug: 0 -> 1 However, I cannot recompile the kernel rigth now for USB_DEBUG. I hope when the failure occurs again the driver be able to say what is going on. I'll be posting the results here. Thanks in advance.
