[First note, I'm not on the list, so please copy me with any replies!]
I apologize if this is a semi-FAQ, but couldn't find reference to it anywhere on the net with search terms I tried, including archives of the list...
I have installed SuSE Linux 10.0 commercial on my Wife's desktop, an Athlon64 3200+ on an ASUS K8V SE motherboard (VIA K8T800 chipset), and in general it's been working well, but I have had a problem that I haven't had time to completely debug myself, but figured there would likely be some knowledge on the list about it:
-- There seems to be a rare but real USB-storage bug in the 2.6.13 series of kernels, and it affects both our Camera and the iPod Shuffle I got her. It causes indefinite hangs of the USB bus after some random amount of data has transferred (usually more than 1 song, between 15 and 100 songs, say), and it also runs the transfers to the iPod quite slowly.
NOTE: I tried using a newer kernel to fix this because I had found references to USB-storage bugs in large data transfers in vanilla 2.6.13 kernels which were fixed in 2.6.14 series kernels. The feeling on the part of those posting seemed to be if there were ever glitches in the transfers, the 2.6.13 series kernel's USB storage drivers just gave up in bad and sometimes unrecoverable ways, and the symptoms to the hangs they observed were the same as the ones I saw.
-- The only fix I could make in the time I have has been to replace it with a later kernel. I have tried both SuSE 10.1 Beta 4 and Fedora Core 4 update kernels (trying to get distribution bug-fixes in).
-- After replacing the kernel, USB-storage works like a dream, fast and no observed hang or hiccoughs...
-- But on the newer kernels, the desktop automounting of USB-storage now is broken.
So, is there some either 2.6.13-specific or SuSE-specific feature which makes the desktop automounting work that I could fix? I patch kernels all the time, just don't have time to fully debug what mechanisms are failing and why... there didn't seem any obvious change in kernel configuration after looking at a few (like KOBJECT_UEVENT, which was functioning fine, and resmgrd was taking events)...
Anyway, would appreciate any info on the topic that could shed light into how to get USB working clean/fast *and* keep desktop automounting working! (preferred solution is getting the automounting working correctly on the newer kernel, I think...)

Of course, as soon as I made this posting, I think I found what it is: it appears to be the "subfs" filesystem, support for which was dropped in later kernels (2.6.15 and later, certainly).
I can just patch it in or probably find a SUSE kernel version that has it which still has the updated USB drivers
