Ok, update, for those who are still reading.

After ripping apart linuxrc, I found that if I only allow usbcore.o usb-ohci.o and usb-storage.o to load it works.  Well I need to boot a bit more, but so far 6 boots successful and counting.

Any ideas?

Conflicting modules perhaps?  If you could narrow it down to the few (maybe only one) that's causing problems, that would help.

Maybe this is also another problem that causes usb-booting problems for other users.  And then perhaps adding a cheatcode (or maybe modifying the defaults outright) to the boot system would make things better.

Sounds like a timing issue. A user had submitted the waitusb option. It is a boot option that you might try. I have no way to test it. Don't know if it really helps.

Another option is to use the dedicated usb minirt24,gz from the bootfloppy-usb.img

Also, did you use syslinux -s or syslinux -ma options when you did the initial setup? Might want to try this as well.

Didn't know that img had a special USB linuxc script - thanks - this will help alot.
Why is this not on the wiki at "installing to USB"?

Will try a bit more with diff sticks and motherboards and report back.  There is definitely some timing issue lurking.

Same issue with minirt24.gz on bootfloppy-usb.img.

The problem module is "ehci-hcd.o".  When I include it it kills the USB stick at insmodding (but not always, so probably a timing issue).
And waitusb didnt do much.
As I understand this is the USB2.0 host controller driver.  So leaving it out should be fine for most hardware out there?
