I have a Sony FileVault USB 2.0 Flash Drive that I use to store working documents on (I don't use the security portion of the drive - if anyone has had one themselves - I was simply able to get it for a steal) that I cannot get working under 4.9 on an HP D530 machine (2.5 GHz P IV w/ on-motherboard USB 2.0 controllers. When I have the machine running, I cannot simply attach the USB Flash Drive and mount it like one would a CD, etc. The machine simply doesn't see the device. I have looked through dmesg and the messages logs to see if it is even seen, but it isn't. What is even weirder, is that if I boot the machine/restart it with the drive attached, the system sees it: Feb 18 16:32:19 hpBSD /kernel: umass0: Sony USB Mass Storage Device, rev 2.00/0.01, addr 3 Feb 18 16:32:19 hpBSD /kernel: pci0: <USB controller> at 29.7 irq 10 BUT, my USB keyboard and mouse no longer respond. I do have all of the appropriate kernel mod's included (da, scbus, etc.), so I'm not sure what is happening. According to a statement in http://www.freebsd.org/cgi/getmsg.cgi?fetch=445988+448507+/usr/local/www/db/text/2004/freebsd-questions/20040118.freebsd-questions USB 2.0 is supported in 5.x and NOT 4.9. If this is the case, why won't the device and the controller simply revert to USB 1.0 or is there something I need to set to get it to work properly (or is the 82801EB controller not able to "play fair" with an os that doesn't support the 2.0 capabilities). In fact, I could care less at this point whether it runs at 2.0 speeds because it's "flash" memory that is only capable of 4MB/s transfer anyway. I would simply like to understand how one can play with the USB setup in 4.9 and see if there is anything I can tweak. (I will eventually upgrade to 5.2 - which, from what I have read, should solve my problems - but before I make the leap, I want to learn more... Any recommendations or ideas? Steve Fettig P.S. Pardon my ignorance on this type of hardware question. I am trying to understand whether "backwards-compatible" is really decided by the software or hardware...
