[SOLVED] iPod not accessable

[desowin]

EDIT: it works like a harm now with "usb_storage.delay_use=1" added to kernel boot line
(this option fixes it both for iPod nad Sansa)

-----

After upgrade to 2.6.22 I am no longer able to mount my iPod. It worked fine with 2.6.20.
EDIT: if I remove EHCI (USB 2.0) support, iPod works fine (if slow can be called fine)

dmesg says

and iPod keeps displaying 'Do not disconnect'
iPod works with older kernels

After upgrade to 2.6.22 I am no longer able to mount my iPod. It worked fine with 2.6.20.

i have same problems with 2.6.21-r4 =(

I'm using 2.6.22 and my iPod is functional.

dmesg output is normal:

dude, could you write a longer post pls?

Code: Select all

# emerge -av nopaste
# cat /proc/config.gz |nopaste
$ paste us a link

[tarpman]

Code: Select all

# emerge -av nopaste
# cat /proc/config.gz |nopaste
$ paste us a link

That should be zcat(1p), rather than cat(1).

[purpler]

damn, you're right, my bad

[stigger]

i solved problem for me. i just connected my iPod DIRECTLY into usb2.0 hub.
