I too am interested in this. I am running EHCI and have had problems with a number of USB storage devices, one of which (the SanDisk Cruzer) causes a crash due to it reporting the maximum LUN as 1. I'm also seeing some interesting performance issues with ext2 being extremely slow compared to FAT.
Additionally, I have been trying various USB hubs with EHCI and have found that a large percentage fail to work. Hopefully I'll look into it more soon when I get ahold of our USB analyzer again.

Hi,

Hi Remy, Still waiting on some boards to try, unfortunately. I expect it will happen in the next 2 weeks though (ARM9 and OMAP4 platforms). Once I get to the bottom of it I will split the patches as requested. I have not seen reports from other users of U-Boot. Also working on USB host Ethernet. Regards, Simon
FWIW: I tested it on Atmel at91 and it does not seem to break OHCI, it does not seem to fix some troubles USB sticks I have here either...
Kind regards,
Remy
