The Knoppix 3.8 from LinuxTag contains 2.6.11-rc3 according to the information on heise.de.
I have strong indications that on Knoppix 3.8.1 it still is 2.6.11-rc3 and not the 'real' 2.6.11.
I have a problem with a libusb based program with the same symptoms (usb_bulk_write fails
with ENODEV) as a kernel bug present between 2.6.11-rc1 and 2.6.11-rc5 when I run my
program under Knoppix 3.8.1.
When I try with the 'real' 2.6.11 kernel my program works.
Can anybody confirm that the kernel on Knoppix 3.8.1 is 2.6.11-rc3?
