[Description frank 2004-10-27 23:28:29 UTC]

with kernel kernel-2.6.8-gentoo-r7 my usb iomega superdvd burner was working fine, but after upgrading to 2.6.9-gentoo-r1 i just get this output from dmesg and no devices:

both kernels have the same configuration.
if it's useful to test with a vanilla 2.6.9 kernel, please let me know...

[Comment 1 Daniel Black (RETIRED) 2004-10-28 00:40:16 UTC]

yes a vanilla kernel test would be hand. Thankyou

[Comment 2 frank 2004-10-28 10:27:27 UTC]

it turns out that i'd accidentally enabled the
Low Performance USB Block driver (BLK_DEV_UB)
while doing "make oldconfig", and that was exactly the cause of troubles.
disabling it gave me back my burner functionality...

Can you please close this?

[Comment 4 frank 2004-10-28 10:52:32 UTC]

i've changed it to invalid...
hope it's right...
