Hi Damien
This patch didn't fix the problem, behaves exactly the same.
I'm using 2 usb sticks for testing: Corsair (32BG) and Doulos (128MB) both
formatted with vfat.
My board contains NXP ISP1520 USB Hub.
Neither of these sticks are being detected correctly, in fact the Corsair is
not detected at all.
By using 'usb start' it detects 3 devices (2 ports and 1 device I assume).
Output from 'usb tree' and 'usb info' gives me not much information but some:
--------------------------------------------------------------------------------

I have tested successfully the Doulos stick on another board with mpc5200 which
don't have any USB Hub, just using the 2 on-chip ports. The Corsair stick is
not working, halts the cpu.

Einar

Hi Elinar,
The root hub is detected and also it detects a device connected to the
controller.
However, by testing with a usbstick (mass storage) it fails to detect the
device as a storage device.
I have here a debug printout which is being printed (with debug enabled) during
execution of the command 'usb start':
Unfortunately, our experience also shows some USB Mass Storage Devices work
better than others. For example, we are able to reproduce some of the issues
we have on the SheevaPlug (Marvel Kirkwood ARM) with the same combinations of
hubs and USB sticks. Do you have another USB Host board available to try to
see if your issue is reproducible across platforms?
Are you able to list the hub and the USB Stick that you are using below? Is it
reproducible across different hubs and sticks? For example, SMSC hubs tend to
exhibit the problems far more than Genesys Logic hubs. I have no experience
with Cypress hubs as to whether they perform any better or not.
If you search the mailing list, I asked about the same issue some time ago.
