All OHCI controllers I've seen are for "OHCI 1.0". :) The spec I use says "OHCI 1.0a", it's not clear what changed between the 1.0 and 1.0a versions. Probably not much... I have a document "Changes from USB Revision 1.0 to USB Revision 1.1", evidently a supplement to an Addison-Wesley book, that can briefly be summarized as: clarifications (intended to match most implementations), enhancements (including interrupt-OUT transfers), and some bugfixes. Nothing listed there "should" affect bulk transfers in particular, as seen with this camera. And since similar problems have been seen with such cameras and UHCI, I'd suspect the issue isn't OHCI-specific. That said, I could easily imagine there's some minor nuance of USB 1.0 support that the 2.6 kernels somehow dropped. Some developer with the relevant hardware and devices would need to track that down. - Dave ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
