USB card reader 6 in 1

[Cornelius Kölbel <cornelius koelbel gmx de>]

Hello list,

I bought a  UCR-61S2B card reader, since it was the extremly cheapest I 
got and since the internet said: "yes it runs on linux".

I installed it on an internal usb port. I am using compact flash cards.
I am running a linux, that was originally a redhat 9 distri. Think it 
changed a bit.
I compiled a new kernel 2.4.22 with - besides others - this content in 
the drivers/usb/storage/unusual_dev.h:

--snip--
UNUSUAL_DEV(  0x1019, 0x0c55, 0x0000, 0x9999,
              "Desknote",
              "UCR-61S2B",
              US_SC_DEVICE, US_PR_DEVICE, usb_stor_ucr61s2b_init,
              0 ),
UNUSUAL_DEV( 0x1019, 0x0c55, 0x0100, 0x0100,
           "ECS",
           "UCR-61S2B",
           US_SC_SCSI, US_PR_BULK, NULL, US_FL_FIX_INQUIRY),
--snip--

Well, now here are my experiences:
- When I insert the cf card into the card reader, the green light 
"access" goes on.
( Is this the correct behaviour?)

I then did some experiments.
I use thes usb lines in my /etc/modules.conf:
--snip--
alias usb-controller usb-uhci
post-install usb-uhci modprobe usb-storage
--snip--

* I insert the CF-Card after booting.
=> I can see all 4 devices /dev/sdb ... /dev/sde in /proc/partitions
BUT! I don´t see any partition of the insertet CF-Card

* I insert the CF-Card _before_ booting
=> I can see all 4 devices and there is a partition sdb1.
But when I try to mount it, it says "no block device".
When I remove the card, sdb1 vanishes. (I think thats OK

* I remove the line with the postinstall usb-storage from teh modules.conf
=> I can´t see any devices in /proc/partitions
I insert the card into the reader
=> I can´t see any devices!
Now i remove the card an do a "modprobe usb-storage".
=> I can´t see any devices
The module usb-storage is loaded. I insert the CF-Card.
=> No devices.

Could be some hotplug problems or module autoloader?
Any hints are very very welcome.

Thanks in advance
Cornelius
