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
