Should I really have four computers all with broken USB > ports? Or else different broken flash drives? I don't know. All I can say is that the usbmon trace shows that the drive you were using stopped working as soon as the computer tried to do a large write. Maybe the drive just can't handle transfers that are too large. You can reduce the transfer size by setting the drive's max_sectors value (the file will be /sys/block/sdg/device/max_sectors, if the drive is /dev/sdg). Trying writing 64 to that file before using the drive.
