USB Cd-rom Install?

Hiya.

I have an IBM Thinkpad 560X that doesn't have an internal Cd-rom. I had a PCMCIA cd-rom, but that recently died. I could only find a USB cd-rom to replace it with. After finally chucking Windoze NT 4.0, I was able to get Mandrake 9.1 up an running on it. However, with 96Meg I was wondering why the Hard Drive light was on all the time. Much to my suprise, the physical memory was full. Hence I'm trying to get back to slackware.

However, with the 9.0 (actually I'm using the unofficial 9.1 discs) install, my USB cd-rom is not being detected, and the usb drivers (or modules) graciously unload themselves before I get the the login prompt. Hence I go into SETUP and it can't find a cd-rom. I'm using bare.i, install.1, and install.2 disks.

1.) Can I prevent the USB modules from unloading themselves?
2.) If not, can I reload them at the prompt?
3.) Does Slackware have a USB Cd-rom autodetect option once the USB modules are up and running?

Thanks for your help guys. (Ain't these quirky install configs great?!?)

Once I get this up and running I'll get back to you on sound cards.

Have you added the cdrom to your /etc/fstab?

In the kernel config file have you uncommented the usb-module section? If not the bare.i kernel will detect the usb device but will not load the modules.

Add the following to your /etc/fstab
/dev/scd0 /mnt/usbcdrom iso9660 ro,noauto,user 0 0
then:
mkdir /mnt/usbcdrom

do an lsmod to see if usbcore and uhci are loaded

uncomment the usb module section in the kernel config:
CONFIG_USB_STORAGE=m (change to y)

save | close | reboot.

I'll try that and let you know how it goes. Thanks.

Mike Doerner

Well, it still unloads the USB modules. I changed the config file like you suggested, but I cannot modify the fstab file because it may be on one of the compressed disks (I didn't see it on bare.i disk)

I also modified some of the other variables in the Config file from m to y, but it still unloaded on me (although it looks like it is finding something, but doesn't know what to do with it.)

Here's the output I see when I boot from bare.i, then install.1....

What else can I do? Mandrake does detect this particular cdrom on it's boot disk. Thanks in advance.

Mike Doerner

I'll try uncommenting the usb section, my printer clipped your response between two pages, and of couse, I didn't see the first sentance.

Mike D

Well, they are uncommented. I'll try switching them from m to y.

did it work?

No it didn't work. Truns out it was my USB card not being seated in the PCI slot correctly.

Now my USB Adaptec card is recognised, but the drive is still not assigned a device so I can mount it. Hre's the output from dmesg....

How do I get /proc/scsi/scsi to assign my USB CD-RW a device? (The HP listed is an IDE drive)

Mike Doerner

PS I'm using Mandrake 9.1 (again)

well.... I assume you can boot from Slackware CD if you can see this log. Why don't your try to load the USB by hand... you know, "modprobe usb-uhci" (or anything else you're using) when you get the prompt where you're suppose to type "setup".
then mount the disk and you should be able to install from the mounted directory... no?

Did you by any change load the usb-storage module?

If not loaded, and after the machine boots, connect your usb cdrom, modprobe usb-storage, and check the log output in /var/log/messages. The log should let you know what scsi device it assigned to it (something like scdX, where X is a number).

Since I am sure you don't have any other scsi cdroms running, mostlikely your usb cdrom will be assigned to /dev/scd0.

At this point, you should be able to mount and access your usb cdrom as if it where a scsi device.

If loaded, check the output from /var/log/messages, and see what goes on when you plug in your usb-cdrom. Maybe there are some errors you are not seeing.

Good stuff guys, I'll give that a shot. However, the HP cdrom already has /dev/scd0, so the USB cd-rw should be /dev/scd1, but it isn't working like that for some reason. I'll let you guys know.

Mike Doerner

OK guys, here's my problem....

The CD-RW never gets assigned an address, and therefore is never assigned a device name. How do I increase the timeout value, or is there some other problem that would be causing this?

Thanks for the help.

I have loaded Slackware 9.1 onto my thinkpad, and tried attaching this USB device that way, and it works!!!!!

However, on my desktop, the Adaptec AUA-4000A USB 2.0 card is new. It seems like it's recognised OK, but then I have the above problem. Any ideas guys?

Mike Doerner

This link can give you an idea of what may be going on.

GL

OK, that is what I will do next. I'll play with the BIOS 1st, look for an updated BIOS second, and lastly move the card around to a different slot.

Thanks for the pointer....
