Hi all,
recently switched to 2.6.0. Trying to get my Card Reade to work, which never had worked under gentoo 2.4.x. Whiel with 2.4 the device was never recognized, I have now some entries in /var/log/mesages: | Code: |
hub 1-0:1.0: new USB device on port 1, assigned address 2
hub 1-1:1.0: USB hub found
hub 1-1:1.0: 4 ports detected
hub 1-1:1.0: new USB device on port 1, assigned address 3
drivers/usb/core/config.c: invalid configuration descriptor
usb 1-1.1: can't read configurations, error -22
hub 1-1:1.0: new USB device on port 1, assigned address 4
drivers/usb/core/config.c: invalid configuration descriptor
usb 1-1.1: can't read configurations, error -22
hub 1-1:1.0: new USB device on port 2, assigned address 5
drivers/usb/core/config.c: invalid configuration descriptor
usb 1-1.2: can't read configurations, error -22
hub 1-1:1.0: new USB device on port 2, assigned address 6

The device is a Sitecom CN300 Card Reader, The USB Product descriptors are:
C0b/a109/1708
C0b/a10c/200
Any Ideas ?

You need 3 things compiled into your kernel.
| Code: | | USB Mass Storage support |
for obvious reasons...
because usb disks need to be emulated as scsi devices (note this functionality is built into the usb-storage driver and thus is unrelated to scsi emulation of ide devices). And lastly:
| Code: | | Probe all LUNs on each SCSI device |
Because you need the kernel to query all n of your readers (otherwise it will stop after the first one it sees).
Toss a couple lines in your /etc/fstab as such:
# flash and smart card reader
| Code: | /dev/sda1 /mnt/compactFlash auto user,sync,noauto 0 0
/dev/sdb1 /mnt/smartMedia auto user,sync,noauto 0 0
/dev/sdc1 /mnt/sdMedia auto user,sync,noauto 0 0 |
and youre ready to mount your cards. You will also want to note this: build usb-storage as a module rather than building it driectly into the kernel. Each time you change out cards (or add cards to the device) you will need to and | Code: | | modprobe usb-storage |
it again in order to mount your new filesystems. |

@MacFlecknoe: got all these Modules you mentioned, even probe all LUN's .
Seems, that the error is in hotplug support
