Hello,

I am running RedHat with custom kernel on the same laptop and it recognizes all these USB hdds just fine.

I tried to boot knoppix from a CD and everything works fine except USB HDD. System just ignores them. lsusb displays just my USB mouse. I tried different HDD enclosures with the same result (all of them work with the RedHat kernels 2.4.28 and 2.6.5). If I try to mount /dev/sda1, it complains that sda1 is not a valid block device.

Here is what lspci says about my USB controller:
00:1d.0 USB Controller: Intel Corp. 82801EB USB (Hub #1) (rev 02)
00:1d.1 USB Controller: Intel Corp. 82801EB USB (Hub #2) (rev 02)
00:1d.2 USB Controller: Intel Corp. 82801EB USB (Hub #3) (rev 02)
00:1d.3 USB Controller: Intel Corp. 82801EB USB EHCI Controller #2 (rev 02)
00:1d.7 USB Controller: Intel Corp. 82801EB USB EHCI Controller (rev 02)

I tried both 2.4 and 2.6 kernels for knoppix. 2.6 displayed some symbol not found errors for usb_storage if I tried expert boot option. The actual ISO image I downloaded today and I believe it is 3.6.

Any ideas?

Thank you,
Nick
