Apologies if I've misinterpreted your advice, I've only been using DesktopBSD for a week. Anyway, after enabling debugging lots of messages similar to the one below appeared in the log after inserting a stick: Jan 17 18:41:33 TekBSD kernel: da0 at umass-sim0 bus 0 target 0 lun 0 Jan 17 18:41:33 TekBSD kernel: da0: < USB DISK 2.0 PMAP> Removable Direct Access SCSI-0 device Jan 17 18:41:33 TekBSD kernel: umass0:umass_cam_action: 11:0:0:XPT_GET_TRAN_SETTINGS:.

I inserted a stick as soon as I had rebooted with the new kernel and dmesg | tail showed the following: afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00 afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00 afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00 And this was in the logs: Jan 17 19:22:46 TekBSD kernel: da0: <Corsair Flash Voyager 1100> Removable Direct Access SCSI-0 device Jan 17 19:22:46 TekBSD kernel: da0: 3.300MB/s transfers Jan 17 19:22:46 TekBSD kernel: da0: 3872MB (7929856 512 byte sectors: 255H 63S/T 493C) Jan 17 19:22:46 TekBSD kernel: afd0: FAILURE - PREVENT_ALLOW ILLEGAL REQUEST asc=0x24 ascq=0x00 Jan 17 19:22:47 TekBSD last message repeated 10 times Jan 17 19:24:31 TekBSD kernel: atausb0: at uhub1, port 4, addr 2 (disconnected) Jan 17 19:24:31 TekBSD kernel: afd0: detached Jan 17 19:24:31 TekBSD kernel: (da0:ata10:0:0:0): lost device Jan 17 19:24:31 TekBSD kernel: (da0:ata10:0:0:0): removing device entry Jan 17 19:24:31 TekBSD kernel: atapicam10: detached Jan 17 19:24:31 TekBSD kernel: ata10: detached The usb sticks I'm using are two corsair flash voyagers 4GB (16mb/s) and one generic 2GB stick (12mb/s). I'm not sure what you mean when you say there is a way to nice/throttle USB transfers now. How would I do that? Hope this means more to you than me, and thanks again. Steve
