Usb-storage And Scsi_mod

[doppiaemme]

Hi!

I'm trying to set up my 7-in-1 USB card reader on my 6000. This device includes a 2.5" HD and works fine on my laptop (2.6.12).

On Z, initially I tried with sd_mod loaded but not usb-storage.
When I connected the USB, with the HD and a SD inserted,  and AFTER modprobed usb-storage, dmesg said:
------------------
Initializing USB Mass Storage driver...
usb.c: registered new driver usb-storage
scsi0 : SCSI emulation for USB Mass Storage devices

USB Mass Storage support registered.
------------------
Then I could mount SD on /dev/sda1 but not the HD!

So I removed the SD, repeated the procedure and I saw:

------------------

------------------------

Uhm, maybe I need scsi_mod.o? I downloaded it from http://www.paipai.org/~humorum/zaurus/modu...scsi/scsi_mod.o
and modprobed it.

So I repeated the above steps (sd_mod and scsi_mod loaded) and when I connected the USB and modprobe usb-storage dmesg said:
-------------------------

-------------------------

The same with or without the SD inserted.
After this I couldn't mount either HD or SD and if I try to rmmod usb-storage it fails!

I don't know if I'm making some mistakes or the scsi_mod I'm using isn't correct or I need to compile something else....

Tips are welcome :-) thanks!

Does your hard drive have the abilty to use external power? I use a 2.5" HD with my 6000 and if I power the drive externaly, it works, otherwise it doesn't. With the laptop however, there is no problem using bus power. I guess the Z just can pump enough power through its usb host. If it uses a Y-connector for usb power you can try pluging the power side into the laptop and only the data side into the hub attached to your 6000. Just a suggestion.
   You may have a different issue though. Did this particular 2.5 " HD work before on the Z's bus power, like under the Sharp ROM?

To see more than one device you'll probably need to recompile the kernel with "multiple luns per device".

I have a 6 in 1 usb-reader but it only ever sees one card at a time on the zaurus

Try rmmodding usb-storage as it controlss the scsi drivers

I can only access the SD cards but not the HD, also when there are no SD inserted. I will try to use another external only-HD unit to check if this is the problem.

I think it isn't a power problem because the unit has its own battery which is used when it can't use USB power. I didn't try the unit under sharp rom because I bought it after flashing to pdaxrom.
