What you're missing is knowing that the USB driver recognizes lots of devices without having anything more than a generic driver for them. This is useful, because userland code can do things with the ugen devices without a driver. If a more specific driver is available, that shows up as well. Here's my USB printer: ulpt0: Belkin Components (2nd) F5U002 Parallel printer adapter, rev 1.00/1.04, a ddr 2, iclass 7/1 The device name is the first part of the dmesg line (ulpt0). The umass driver should work for this device, as it claims to handle ATAPI drives. If it does, you'll get a "umass0" device. If it isn't, it may be a quirk in the drive, and that will have to be fixed in code. Either that, or the USB-ATAPI bridge isn't a umass ATAPI device, in which case you're out of luck. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
