Coasters when using USB2-based CD Burner

I got a new 48x USB2-based CD burner at the same time I downloaded the CDA5 Beta. (I had been using a Firewire-based 16x burner.)
Two observations:
(1)Vegas 3 doesn't work properly with the USB burner at all. Will USB support be added to a later Vegas release? (The drive works fine with Nero.)
(2)With CDA, about 20% of my burns on this drive produce coasters. I'm guessing this is because of the "known problem" mentioned in the Beta release notes, that CDA fails to recognize buffer-underrun-prevention support on some drives. On my older Firewire drive, CDA's "Buffer" display field is active when I burn a CD, but with the USB drive it's not. I'm hoping that the promised fix for recognizing buffer-underrun-protection will fix my problem. Are my expectations realistic?

Please report all issues to:

CDArchBeta@sonicfoundry.com

These e-mails go directly to the CD Architect engineers, so that is your best bet.

earthrisers,

Which brand of USB burner did you get?
I'm looking at buying a Plextor USB drive and was
wondering if anyone is having trouble (or no trouble)
with it.

This one: PlexWriter 48/24/48U Hi-Speed USB CD-RW drive.

Earthrisers, I'm trying to use a USB2 based plextor drive (the older 24/10/40) and cant even get cda 5 to see the drive! Is ur drive a plextor? What windows version are u running (in win 2k)? Did u have to remove any cd aware software to get the CDA beta to run?

The CDA beta team has been responsive, but un-siccessfull.

Other burn software i've used (like roxio or nero) haven't had an issue with the plextor.

thanks

The USB2 drive I got is a brand I hadn't heard of before -- Artec. It includes an ostensibly recent technology or protocol called "JustLink", supposed to absolutely prevent buffer underruns.
It works quite well with Nero. Vegas' CD-burn function doesn't recognize the drive at all.
I also have a Firewire-based burner, with which CDA and Vegas both work just fine (but it's not rated as fast as the newer USB2 drive).

My operating system was WinXP Home Edition, when I posted this report. (I've since upgraded to WinXP Pro, because I need the ability to test data-driven websites on my local machine, and Home doesn't support that.)
I haven't downloaded the second Beta release of CDA, so I don't know whether that fixes the problem. I may or may not have a chance to download & play with that one, before its upcoming Nov.8 expiration date.

I realise it's just a hang-over from USB1, but given the flakiness of the whole USB subsystem (cpu-hits, etc) I wouldn't be seen dead with a USB drive that required real-time streaming with software that requires heavy realtime processing.


Just found I can't even preview with Izotope Ozone in realtime on a P533....
