Well, call me an amateur. <blush> Forget about the bad-performance-because-of-disk-trashing story. I had turned on a lot of debugging, and the syslog daemon was configured to sync after every debugging log record. This will garantee that every last record hits the disk, but it will also trash your disk in the process, 100% garanteed. :-) So it works. Throughput: 54044 bytes/second (3 files, 1987072 bytes total. Not really great, but much faster than via an asynchronous serial port. Thanks for your assistance. If you want me to investigate the problems with USB-UHCI any further, just ask. Regards, Toon. -- /"\ | Windows XP: \ / ASCII RIBBON CAMPAIGN | "Sorry Dave...
