I've the same problem with a 64bit version of Ubuntu Natty (11.04), and a Huawei E165G USB HDSPA modem. I think that the problem is in the kernel module, because of this message: "kernel: [ 287.000190] option: option_instat_callback: error -108" The USB device is reseted every 15-20 secs, with 5 or 10 secs of freeze.
