List V3.8.1 bugs here
1. No USB keyboard support on Dell Optiplex GX280.
Some hardware details:
* USB Keyboard: Happens to be a Danish keyboard, shouldn't matter. * SUSE identifies the keyboard as "Dell USB Keyboard Hub" and uses the hid driver * USB Mouse * Pentium 4 * SATA hard drive
symptoms:
* Keyboard works at the "KNOPPIX: " boot prompt, anything after that it doesn't
* above the "Welcome to KNOPPIX... (etc)" white text line, you have:
1. image of tux
2. audit(somenumber.???:?)
3. ata2: disabling port
it's that 3rd line that perplexes me.
* Hangs 30 seconds into booting, immediately after message: "2.78 Knoppix booting"
* It seems it never detects anything USB (though the USB mouse kinda works later...)
* booting "debug" asks to type exit to continue... nothing responds on the keyboard
* booting "failsafe" makes it all the way to KDE where the mouse (mostly) works, but the keyboard does not.
* booting "expert" fails when it needs KB input to select SCSI drivers.
* booting the {nousb|nousb2|lang=da} all fail.
* booting "knoppix testcd" fails similarly
* booting "failsafe testcd" tests the CD and makes it into KDE as prev. mentioned
ideas:
* ?? I've tried a lot of tweaking and some searching, anyone experiencing similar issues? * Is anyone having success with 3.8.1 and a new Dell?

With knoppix 3.8.1 (english) on an IBM x335 machine and console attached via a console chain cable the keyboard becomes inoperative after Knoppix has booted. After the CPU tuxes the following lines are written to the console:
i8042: Can't read CTR while initiating i8042 ide2: I/O resource 0x1E8-0x1EF not free ide2: ports already in use, skipping probe
This did not happen with Knoppix 3.4 (english). Just to let you know. For further information please write: jvwCHANGETHISTOATSIGNiwr.fzk.de

If you open K Menu -> KNOPPIX -> Utilities you will see "Chose/Restart KNOPPIX Desktop." That should read "Choose/Restart KNOPPIX Desktop." Just a small typo, but it seems to have escaped the developer's watch in the last few releases.
4. USB2.0 Storage device slow speed
[CLH] USB2.0 external hard disk is auto-mounted as ub device, which is using USB 1 transfer speed, far slower than using sd_mod. for example, trying to mount /dev/sda1 gives error because module sd_mod is not available (modprobe sd_mod gives error) should recompile kernel with scsi module (sd_mod) support. Also check out the usbmount http://usbmount.alioth.debian.org/ which automount external USB storage devices , I tried Ubuntu liveCD and it worked well at USB2 speed.
