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.
