I had a lot of problems with the USB ports on my Windows box's motherboard (it's a Pentium MMX, it has USB headers but not the actual ports, and of course they are proprietory). I ended up buying a USB PCI card and putting it in there. Well I'm sure you don't care too much about my Windows problems, but the short of it is it didn't work with the PCI card - it would burn for a while then the drive would appear to reset and I'd get a bunch of SCSI errors. Now this box is underpowered compared to the minimum specs, but I don't hold much truck with them :-) Anyway in light of my failure, I decided to try it my FreeBSD box (which is only a 486-100!). After moving the PCI card and (slowly) compiling in USB support, I'm happy to say it detected the drive and mounted pre-recorded disks no problem. This is 4.2-BETA. I compiled up the cdrecord port and gave it a test. It seemed to have exactly the same problem! It maybe went a bit further, but then the drive would clunk, and I'd get SCSI errors. This would actually be quite bad as it would (I didn't narrow down the exact circumstances) in some places completely crash the box - I think it was after unplugging the drive after it reset. I'm starting to think at this stage that the drive was faulty, but I took it to a friend with on-motherboard USB ports and it worked flawlessly. So I guess what I'm asking is do I *really* need a PII-266 as the burner box suggests? It seems ludicrous that you need something like that to send just 150K/second to a device. In all my tests I eventually downgraded to burning at 1x and never (in either Windows software or cdrecord) did I see the buffer go under 95% Other information that may be important, PCI USB card (the only common factor in my problems) has a VIA 83C572 chipset, it uses the uhci device: usb0: on uhci0 usb0: USB revision 1.0 Does anyone think this could be the problem? Thanks for any help anyone can offer.
