Georg:
Yes, I did runtime test those patches, however:
- all of the patchset then went in in May release were done against
AT91SAM9G25 SoC and I haven't had a chance to convert SAMA5D3 related
code to leverage those changes.
- pure OHCI, (i.e. EHCI being disabled) never worked for me on AT91 (I
never debugged it since I didn't care about getting OHCI to work) and
the only thing that this driver was needed for was to configure VBUS
related GPIOs that are shared with EHCI. Using EHCI on SAM9G25 _did_
work and I was able to read/write data from/to a USB pen-drive.
Hope this is gives you at least some answers.
Thanks,
Andrey Smirnov
