</span>UAS ... google ... wikipedia ...<br>
Well, it would be the natural way to perform SG_IO with a USB<br>
device. Burn programs issue SCSI commands and UAS is designed<br>
for transporting them. Wikipedia has:<br>
"Version 3.18-rc4 of the Linux kernel disables buggy UAS<br>
implementation in xHCI host controllers Etron EJ168,<br>
ASMedia ASM1042,[19] and VIA VL80x.[20]"<br>
<br>
But i understand that UAS is quite a new protocol.<br>
Is your drive's USB controller young enough ? (Actually<br>
i assume the drive is SATA or IDE and the box has a<br>
USB-SATA or USB-IDE bridge bridge.)<br>

<br>
</span>They really give few clue about age and version of the<br>
drive-side USB controller.<br>
I googled for "PLEXTOR USB Storage Adapter" "UAS" and found<br>
nearly nothing. Descriptions of UAS refer to hard disks and<br>
SSDs, rather than optical drives. But - as stated - i expect<br>
it to depend on the USB-SATA or USB-IDE controller of the<br>
drive box.<br>
<br>
<br>
In any case, recent changes in USB are obvious suspects.<br>
Now i'm curious whether the working and non-working Linuxes<br>
show a pattern with kernel revisions.<br>
