Errors trying to mount USB Mass Storage Device
 

Alright, here's what's up... I'm trying to mount a USB Mass Storage device (just installed Slackware 9.1 and trying to get things up and running), but am not having much luck with a few things.

It seems that the device is recognized in the Info Center (KDE's), it shows up as a USB Storade Device and so on, however, I don't think it mounts it for me or anything of the like.

So when I go to mount it (after trying to load modules, editing fstab, so on), I get the error that /dev/sda4 is not a valid block device. I would assume that I am getting this error because a few of the modules I should have I don't think I do (scsi_mod, sd_mod, and also modprobe usb-uhci or scsi-uhci generates a list of errors).

Any ideas? Should be around, let me know if you need more (dmesg output, etc)

Here are two good thing to check.
cdrecord --scanbus
fdisk -l

Got an error of : Cannot open SCSI driver for cdrecord --scanbus, and fdisk -l just lists my normal partitions (this is just a pendrive, dunno if it should show up there or not). Right now I'm running around trying to find my missing modules with little luck.

If all is well, both commands should list the drive.
I would think the "Cannot open SCSI driver for cdrecord" is the problem.
Here are the kernel modules I have on my Debian system:
ide-scsi
usb-storage
usb-uhci
usbcore

Anybody know where i can d/l the modules? I can't find a good place online.

# modprobe usb-uhci
/lib/modules/2.4.22/kernel/drivers/usb/host/usb-uhci.o.gz: init_module: No such device
/lib/modules/2.4.22/kernel/drivers/usb/host/usb-uhci.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.22/kernel/drivers/usb/host/usb-uhci.o.gz: insmod /lib/modules/2.4.22/kernel/drivers/usb/host/usb-uhci.o.gz failed
/lib/modules/2.4.22/kernel/drivers/usb/host/usb-uhci.o.gz: insmod usb-uhci failed

???

Look at the output from dmesg. What are the errors for USB?

Your USB controller might use usb-ochi or if its a USB 2.0 controller usb-echi.

Alright, so I'm using Redhat 9.0 now, but I still have the same basic errors.

When I cat /proc/scsi/scsi, it returns that no devices are attached, however when I cat proc/scsi/usb-device-0/0 I get
Host scsi0: usb-storage
Vendor:
Product: USB Storage Device
Serial Number: 0AEC301000001A00
Protocol: Transparent SCSI
Transport: Bulk
GUID: 0aec50100aec301000001a00
Attached: Yes

So it'sbeing recognized, but not quite right. Any ideas?
