Hi there, I just joint the list and I have a question about my DVD burner. I tried several kernels and hardware with the following success (??):
1. If I replace the DVD burner by a harddisk everything works (on all testet hardware & kernels) 2. Everything works under USB 1.1 (on all tested hardware and kernel) 3. USB 2.0 does work in kernel 2.4.19 (hardware of a friend). But not in kernel 2.4.22, 2.4.22-ac4,2.4.23-rc4,2.4.23-rc5,2.6.0test9-11 (all tested hardware). Therefore I conjecture that the problem is in the ehci-hcd module. Unfortunately, I cannot use kernel 2.4.19 on my laptop since my USB2.0 cardbus adapter doesn't work in this kernel. cat /proc/scsi/usbstorage-?/?
