Hello Stelian,
Thanks, and I expect to hear some more positive news ;-)))
I'm afraid I have more bad news.
Grmbl, Now my weekend is ruined ;-))))
Sorry for that :)

Okay, let's summarize this: With and without patches it does not work on AT91CAP9 and AT91SAM9263... (Without my patches you get a less detailed error message...)
Right. However the two board fail with slight different errors iirc.
There can be several reasons for this:
- The USB code never worked on AT91CAP9 and AT91SAM9263 with mainline,
so it could be possible that there is some initialisation missing for CAP9 and SAM9263, possible for more CPU's also that did not work before with GCC 3.x.
Sure. However, I've double checked the Linux initialisation code for the usb host on the AT91 boards and the U-Boot counterparts and there are only a few differences (some VBus GPIOs to set on the AT91SAM9263, an additionnal clock for AT91SAM9261), and I cannot find anything which could go wrong here.
Does not mean the patches are bad, but does mean that it could be possible/likely that these patches do not fix all problems for all boards and all sticks.
Sure.

I want to invest some time in it to debug these issues also, but then I will need your help, because I do not have a SAM9263, CAP9 board so I cannot reproduce your problems here.
I do have a SAM9263 in front of me waiting for your experimental patches :-)
And I can do some extra tests on other Atmel boards, but this will have to wait a week or so because I won't have access to them before then.
I have several ideas where to look, and can create some experimental patches, but before I do that and bother you unnecessary, I would like to get some more information from you about which USB sticks you are using.
I tested with 2 different USB sticks, a very old 256 MB one and a more recent 1 GB. They behave exactly the same.
Can you please provide me the output of: (even if the command fails)
- usb info
- usb storage
- usb tree
- and if possible a 'lsusb -v' output from linux of your USB sticks
See below.
Also, it would be very helpful if you would test your sticks on a SAM9261, because that SoC _must_ work. (I tested on AT91SAM9261-EK, and custom board) Then we can relate the problem to a specific USB stick, or to a certain SoC.
Hmm, I can do that, but not before September 29.
Stelian.
