Unless I compile in ohci along with ehci, I get the following error: gravy kernel: usb0: wrong number of companions (2 != 0) Using both ohci and ehci results in probing the attached devices twice, then removing the ohci device in favor of the ehci device. So, in the dmesg, I see my usb hard drive twice, assigning umass0, then umass1. After umass1 is assigned, umass0 is then detached. kernel: umass0: Buslink USB 2.0 Hard Drive, rev 2.00/11.00, addr 2 kernel: umass1: Buslink USB 2.0 Hard Drive, rev 2.00/11.00, addr 2 kernel: umass0: at uhub2 port 4 (addr 2) disconnected kernel: umass0: detached Is this the intended behavior? I've been using a partitioned off usb hard drive as a tape device, just using the raw devices as tapes. (Much cheaper than a tape drive). My nightly dump caused a panic, although shorter transfers seem ok. I found this in messages: kernel: umass1: Invalid CSW: sig 0x00010001 should be 0x53425355 Sorry I don't have more info at this time, I've been flooded at work and haven't had the time to reproduce and create a core dump yet. Finally, I see no difference in speed between the 1.0 drivers and the 2.0 drivers. -- ============================================================= = Bryan D.
