Booting Knoppix-3.9 with scsi emulation for USB?
I am fed up with the nasty ub support in the Knoppix kernel.
The Knoppix-3.9 kernel is compiled with CONFIG_BLK_DEV_UB=m by default. As a result, it masked all usb-storage devices and USB devices are no longer identified as /dev/sdaX, but /dev/ubaX.
This ub support is really a bitch. On the one hand, it is unstable, the data transmission rate will graduately decrease and eventually painfully slow. On the other hand, I am unable to install Knoppix directly from CD into a USB HDD because GRUB is not able to identify a /dev/ubaX for installation.
I tried to boot Knoppix with the nousb option and then modprobe all the other USB modules such as usbcore, usb-storage, usbhid, ohci-hcd, ehci-hcd and uhci-hcd etc except the ub module afterwards. No luck! All the USB modules are installed without error but /dev/sda1 still cannot be identified as a valid block device.
Installing the ub module, then my USB HDD works again but it becomes /dev/ubaX again!
Without installing Knoppix into HDD and get rid of the ub by re-compiling the kernel, are there any methods to boot Knoppix-3.9 without the ub, i.e. with SCSI emulation for USB again? Alternatively speaking, are there any methods to enable Knoppix-3.9 to identify USB storage devices as /dev/sdaX again?
Thanks in advance.

Re: Booting Knoppix-3.9 with scsi emulation for USB?
I have a similar problem with booting from USB-CDROMS.
Hardware are Dell X300 / Toshiba R100 both Laptops with no internal CDROM.
I can boot fine with older KNOPPIX Versions and the 2.4 Kernel and every USB-CDROM/Burner.
But every 2.6 Kernel ends with with:
Cant find KNOPPIX filesystem, sorry.
If there are no methods to boot without ub support. Is it possible to remaster KNOPPIX with a recompiled Kernel without ub support?
Thanks

I am having the same issue! Someone Please Help! I only have USB CD-Roms and no internal CD-Rom so I am limited to 3.7.

Remastering Knoppix with a recompiled kernel without ub is definitely a solution. In fact, I can install Knoppix-3.9 into a USB HDD by installing it to a HDD, replicate it into USB HDD and then replaced the kernel with a custom kernel. This is a very tedious solution. Actually, installation from Kanotix to USB HDD is straight forward.
I just wondering if there are any possible way to boot without ub support.

Like Kanotix, in Knoppix 3.9, you can use the bootusb2 boot option to boot Knoppix from USB CDRom. So, boot Knoppix with:
knoppix bootusb2
