BTW, looks like this might be filed as: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/102659 with ubuntu... Aww, man, I forgot to ask what was the last kernel that worked. We should've saved it and re-tested now. Yeah, I meant to go back and figure out when it broke, but I didn't. ;( I can try and go back and see what kernel broke it. Not going to be easy though. ;( Sorry for the delay here. Now I have waited to the point where it's gonna be hard to find the older kernels to test. This still occurs with the latest f8 update kernel: kernel-2.6.21-1.3228.fc8.x86_64 Is there any further info I can gather that would help tracking this down? Or is there a specific kernel you would like me to test with? We can do two things 1. Rebuild the RPM carefuly with CONFIG_USB_SUSPEND disabled, but without changing anything else, see if that helps, and 2. Get usbmon trace with which I could go to linux-usb-devel. This needs not rebuilds. There's a howto here: /usr/share/doc/kernel-doc-2.6.21/Documentation/usb/usbmon.txt ok, #2 sounds easy... I am attaching the usbmon trace. I started it and did some lsusb's and watched the device appear and disappear a few times.

usbmon output from bus 2t
Here's the usbmon trace

There are devices that require quirks to work with it enabled, and we'll be forever chasing those if we leave it enabled. Mental note: see also 243798 (don't dup just yet, please!) Sorry to leave this one around... works just fine these days. I am going to go ahead and close this bug... |
