Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Keyboard and mouse don't work after USB boot


I'm suffering from a weird problem I can't solve.
I installed SLAX-live to an USB-stick, and made stick bootable. This way I could easily change the used modules etc.
However, when I boot from the USB-stick, SLAX boots OK, but I can't login because the keyboard does not work. It works during the menu where I select how to boot (KDE / console), but after the actual boot and hardware detection, nothing. The keyboard I use is a Logitech Media Keyboard PS/2, and I also tried with and older KeyTronic, with the same result.
Also, if the USB-stick is plugged in, Ubuntu 6.10 install suffers from the same problem - boot up, start the live CD, then no control whatsoever.

I assume that this is some kind of hardware conflict with USB / PS/2 that comes up during the HD detection?

Here's the hardware:
ASRock K7S8X
Athlon XP 2400+
1GB DDR 333
2x Seagate 160GB IDE
Asus GeForce 6600GT
SB Live! 1024
3Com Etherlink XL 10/100 PCI
Logitech Media Keyboard (ps/2)
Logitech MX700 (USB)

Sandisk Cruzer Micro 512MB USB-memory

I should also mention that I'm not a hardcore linux-user, so I may need simplified answers and I propably will ask stupid questions.

Anyway, any help is greatly appreciated.

I don't know SLAX, but I think the problem may be in the kernel of that distro. After the initial BIOS support for the keyboard (which seems to work as you say), the freshly booted kernel on the stick needs to provide support for USB keyboards and mice. Perhaps it doesn't. It needs that HID section in the kernel (Device drivers-> USB support -> Human Interface Device) enabled, in addition to the actual USB drivers for your hardware. Can you check?
