    My Nslu2 (Linksys v2.3R63) doesn't recognize a Thecus N2050 usb drive plugged into usb 1 (drive 1) port.

    The N2050 is a dual drive RAID box using two Seagate ST3200827AS (200MB) SATA drives. The N2050 RAID 1 array was partitioned (1 part 200GB) and formatted (NTFS) when attached to a WinXP machine, and it worked fine there. The processor in the N2050 is a Silicon Image 4723 Steel Vine RAID-Controller and it presents the host machine (Nslu2 or a PC) a single drive view of the dual RAID array in the N2050 ... so, there's no dependency for RAID software in the host device. A 512MB flash drive is plugged in and recognized on usb 2 of the Nslu2.

    So, both devices (Nslu2 and N2050) appear to work fine independently, but they don't work together.

    What would be some steps to make the Nslu2 recognize the N2050 on usb 1 ?

    Will there be a better chance of getting the Nslu2 + Thecus N2050 to work by loading a non-Linksys OS (Unslung, Openwrt, etc.) ?

    It is possible the USB-to-drive controller is not being recognized by the NSLU2. There are a few of these chipsets that the NSLU2 doesn't recognize for some reason. If you read through some of the old NSLU2 threads here you will see various USB drives and USB drive enclosures that wouldn't work. The Yahoo NSLU2 group even had a list of chipsets that would and wouldn't work.

    I don't think anyone ever reported here a method of getting one of these problem chipsets to work with the NSLU2. This is with either stock firmware or third party firmware. The only solution some people found was to buy a different USB drive.

    One thought that I've had was maybe it might be possible to place a USB hub between the NSLU2 and problem USB drive and have it work. I've heard of this trick working for ethernet ports where certain routers had a WAN port that was picky about the electrical parameters of the connecting modem port and an ethernet hub acted as filter to fix the problem. Admittedly this idea would be a long shot to solve your problem.

    There are some known differences/limitations of the slug us ports - so they make work in a different order. Why not try the current Linksys firmware first?

    chipset compatibility

    Where is the "Yahoo NSLU2 group" and the chipset compatibility information ?

    chipset compatibility

    The compatibility database doesn't seem to be there anymore. I am a member of http://groups.yahoo.com/group/nslu2-general but I get this message when browsing to http://groups.yahoo.com/group/nslu2-general/database :
    You are not a moderator of the group nslu2-general
    And, I don't see "database" in the navigation panel at the left of the nslu2-general group page. Maybe the database was removed ?

    Where might another copy of the database be ?
