Hi, I have problems getting an external USB disk enclosure to work properly with OpenSolaris/SPARC.
The unit identifies it self as Prolific Technology Inc. Mass Storage Device (usb67b,2506) (http://www.prolific.com.tw/eng/Products.asp?ID=69) The device is known to work properly with Window Vista and the external disk is formatted with an NTFS filesystem. dmesg shows this: Mar 31 17:31:45 odin usba: [ID 912658 kern.info] USB 2.0 device (usb67b,2506) operating at hi speed (USB 2.x) on USB 2.0 root hub: storage at 6, scsa2usb0 at bus address 2 Mar 31 17:31:45 odin usba: [ID 349649 kern.info] Prolific Technology Inc.

Have I overlooked something or is the device not supported properly by the scsa2usb driver? I'm running an older version of OpenSolaris (SunOS odin 5.11 snv_90 sun4u sparc SUNW,Ultra-5_10).
