usb mass storage fails in 2.5.18

usb mass storage fails in 2.5.18

[jay]

I'm trying to set up 2.5.18 to read a digital camera memory stick - 
which I can in 2.4.18.

I think I've configured the kernel correctly:

#
# SCSI support
#
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
CONFIG_SD_EXTRA_DEVS=40
# CONFIG_CHR_DEV_ST is not set
# CONFIG_CHR_DEV_OSST is not set
CONFIG_BLK_DEV_SR=y
# CONFIG_BLK_DEV_SR_VENDOR is not set
CONFIG_SR_EXTRA_DEVS=2
CONFIG_CHR_DEV_SG=y
CONFIG_SCSI_MULTI_LUN=y
CONFIG_SCSI_REPORT_LUNS=y
CONFIG_SCSI_CONSTANTS=y
# CONFIG_SCSI_LOGGING is not set
.
.
.
.
#
# USB support
#
CONFIG_USB=y
CONFIG_USB_DEBUG=y
CONFIG_USB_DEVICEFS=y
# CONFIG_USB_LONG_TIMEOUT is not set
# CONFIG_USB_BANDWIDTH is not set
# CONFIG_USB_DYNAMIC_MINORS is not set
# CONFIG_USB_EHCI_HCD is not set
# CONFIG_USB_OHCI_HCD is not set
CONFIG_USB_UHCI_HCD=y
# CONFIG_USB_AUDIO is not set
# CONFIG_USB_BLUETOOTH_TTY is not set
# CONFIG_USB_ACM is not set
# CONFIG_USB_PRINTER is not set
CONFIG_USB_STORAGE=y
CONFIG_USB_STORAGE_DEBUG=y
# CONFIG_USB_STORAGE_DATAFAB is not set
..............


And the kernel sees it on bootup. See the dmesg snip below. But there is 
nothing in /proc/bus/usb. OTOH /proc/scsi/usb-storage-0 does exist. When 
I try to mount /dev/sda1 I get it's not a valid block device.

Can I get this to work? What am I missing?

thanks for any help
jay

Re: usb mass storage fails in 2.5.18

[Joseph Pingenot]

I've also had problems with 2.5.17 (haven't tested 2.5.18) and a USB
  ZIP drive (Zip 250 USB-powered).  It looks like a write operation times
  out, and the drive keeps getting reassigned new USB device numbers.  I
  can provide more info if anyone's interested.  I *do* recall that it's
  something like bulk_write, and it fails with error -110.
