I have a V-link drive box that houses a hard disk.
The interface is up to USB 2.0 compatible.
I purchased this from CompGeeks. :-)
A friend of mine got this working on Mandrake Linux without any
additional
drivers. When I try to use it on RedHat 7.3 (kernel 2.4.18), the USB
driver
sees it get plugged in as well as when it's unplugged. But the message
in
the /var/log/messages reads:
Feb 13 19:19:23 blueboy kernel: hub.c: USB new device connect on
bus1/1, assigned device number 3
Feb 13 19:19:23 blueboy kernel: usb.c: USB device 3 (vend/prod
0x67b/0x2307) is not claimed by any active driver.
Feb 13 19:19:27 blueboy /etc/hotplug/usb.agent: ... no modules for USB
product 67b/2307/100
I have usb-storage, ide-scsi, and usb-uhci all loaded as modules.
Everything I've read on the internet that I can search for in google
tells me
this should just simply work and give me the drive as /dev/sda (I have
no other
SCSI devices), but it isn't happening.
Has anyone made one of these work?
Thanks.

You need to have either the OHCI or UHCI module loaded for USB 1.1
support (which you obviously do). _In addition_ you need the EHCI
module (ehci-hcd) to support USB 2.0 speeds. Check with 'lsmod'. If
it's not listed, try (as root) 'modprobe echi-hcd'. If you see no
output, the module loaded successfully; try plugging in the scanner
now. If there is output from modprobe, report the errors here if you
need further help resolving the problem.
The rebading by the USB peoples means:
USB 2.0 Low-speed = USB 1.1 <12mbits
USB 2.0 Full-Speed = USB 1.1 12mbits
USB 2.0 Hi-Speed = USB 2 480Mbits
