Hi,

i followed the usb storage howto 2 times and did search and read stuff here on the forum for 4 hours to rule out any mistakes but i really cant get my USB Maxtor Onetouch 2.5" going!!!

HW Data is:

ASUS WL-500G Premium with most recent Whiterussion stable (0.9) and x-wrtg.

The system is able to detect and mount a 256MB USB Ramstick (ext2 fs + swap), detect and mount a Cardreader with a 2GB SD Ram Card (vfat fs) but when i insert the HD i only get errors.

"lsub" detects the HD:

Bus 001 Device 001: ID 0000:0000  
Bus 001 Device 004: ID 0d49:7250 Maxtor 
Bus 001 Device 005: ID 0dda:2005 Integrated Circuit Solution, Inc.

(See next posting for lsusb -v details)

But when i inser the HD i get tons of errors and no "/dev/scsi/...lunx/part1" etc. device. Only a "/dev/scsi/...lunx/disc" entry. Needless to say that the HD works well under Ubuntu and Windoozes. The HD has 2 ext2 partions, one swap partition and one large (127GB) vfat partition.

Heres the head of the error message (again see next posting for full dmesg output)

One more Question: Most of the USB 2,5" HDs seem to have two USB connectors for sucking electricity. Are there HDs know to work with only one USB Plug? Should i invest into a power adapter for the HD or should i buy an USB Hub?!

thx,

I can confirm this. My usb disk sometimes (Not always, strange enough) need 2 usb connectors to spin up. After the spinning up I can remove the other connector.

Ok fiddling around with hardware and software setup i discoverd that, depening on how i connect the maxtor usb harddisk to the ASUS WL-500gP i get different dmesg logs :(

If i boot it up with the USDB harddisk connected with both USB plugs the HD is at least recognized by the scsi driver:

hub.c: new USB device 01:03.2-1, assigned address 2
scsi0 : SCSI emulation for USB Mass Storage devices

but then fails with:

usb_control/bulk_msg: timeout                           
scsi: device set offline - not ready or command retry failed after bus reset: host 0 channel 0 id 0 lun 0
WARNING: USB Mass Storage data integrity not assured                            
USB Mass Storage device found at 2

I now go and buy an USB hub in case all this problems are due to the powersupply is not efficient.

As i said, the HD connects well to other Linux and Windows boxes when only using one usd plug and the ASUS WL-500g can use other USB devices like Mem-Sticks and Cardreaders with SD Cards.

This suxs....

I can confirm this. My usb disk sometimes (Not always, strange enough) need 2 usb connectors to spin up. After the spinning up I can remove the other connector.

Good to know but is it better to go and buy an external powersupply for the HD or should i buy an USB hub with external powersupply?

And why isnt there indicator on the disc so i know if it has enough power or not? The maxtor onetouch has an LED and ist on even if it doesnt has enough power. This USB stuff with openwrt on embedded devices is really driving me nuts....

cheers,

I am going for an external adapter 2 but basicly because I want to silence the damm thing so I can sleep without the annoying thing around my head.

No real change when connecting the USB HD via an external USB 4 port hub with external power suppy. When i disconnect the power-supply and reconnect it i get the same error messages than before

But now the system creates the following device entries:

/dev/scsi/host1/bus0/target0/lun0/disc
/dev/scsi/host1/bus0/target0/lun1/disc
/dev/scsi/host1/bus0/target0/lun2/disc
/dev/scsi/host1/bus0/target0/lun3/disc
/dev/scsi/host1/bus0/target0/lun4/disc

which it didnt create before. Not that it helps because the partitions are obviously missing....

/proc/partitions looks like this btw:

major minor  #blocks  name
 
   8     0    1048575 scsi/host1/bus0/target0/lun0/disc
   8    16    1048575 scsi/host1/bus0/target0/lun1/disc
   8    32    1048575 scsi/host1/bus0/target0/lun2/disc
   8    48    1048575 scsi/host1/bus0/target0/lun3/disc
   8    64    1048575 scsi/host1/bus0/target0/lun4/disc
   8    80     245248 scsi/host2/bus0/target0/lun0/disc
   8    81     187984 scsi/host2/bus0/target0/lun0/part1
   8    82      56800 scsi/host2/bus0/target0/lun0/part2

Anyone has any idea whats going on?! Any pointers where to look for?

I am again searching the openwrt.org (and other sites) for information and did run over this open tikcket concerning the Kamikaze release with the same kernel:

Anyone can help me with this topic?!
